Winter checklist for NEMT vans: tires, lifts in the cold, and a kit for stranded riders
A winter checklist for NEMT vans covers four areas before the first freeze: tires (tread, cold pressure, and the chains or traction devices your state requires on snowy routes), the battery, coolant, heat, and winter washer fluid, lifts and ramps kept clear of ice and serviced more often, and a kit of blankets, water, a shovel, and sand for riders if the van gets stuck.

How to use this checklist
Winter work on a NEMT van happens in three places: the shop in the fall, the lot every cold morning, and the cargo area where the emergency kit rides. This sheet has a part for each, plus a card for the day a van gets stuck.
- Part 1, fall preparation. Done once per van before the first freeze. Minnesota’s equipment rule starts its ice scraper season on October 1, which is a sensible deadline anywhere it snows.
- Part 2, lifts and ramps in ice. Added to the daily lift check from the first frost until spring.
- Part 3, the daily winter pre-trip. Done by the driver every shift while temperatures sit near or below freezing.
- Part 4, the stranded-rider kit. Loaded in the fall and checked monthly.
Whether to run, delay, or cancel trips on a storm day is a separate decision, covered in the bad weather policy guide. This sheet keeps the vans ready for whatever that policy decides.
| Vehicle | Unit number | Fall prep done (date) | Checked by |
|---|---|---|---|
Part 1: fall preparation
Shop visit
- Coolant strength tested and topped up
- Washer reservoir filled with a winter blend that will not freeze
- Battery load-tested, terminals clean and tight
- Oil grade matches the manual’s cold-weather recommendation
- Heater and defroster at full output, with warm air reaching the rear seats and wheelchair stations
- Brakes and brake fluid inspected
- Exhaust system checked for leaks
- Ignition and starting system checked
- Headlights, tail lights, and hazard flashers working
- Wiper blades replaced if they streak or chatter
The list builds on the fall checks on CDC’s winter storm preparation page (updated December 2, 2025) and adds items riders and brokers care about, such as heat at the rear. The battery deserves the most attention. The federal fuel economy site notes that battery performance falls in the cold, which makes it harder for the alternator to keep the battery charged, and a wheelchair lift draws on that same battery. Heat is a broker standard as well as a comfort issue: Virginia’s fee-for-service requirements (updated May 26, 2026) judge the heater by a reading taken from the back of the van, which must reach 74 degrees, and Minnesota requires every heating unit a van has to work (Minn. R. 8840.5950).
Tires and traction
- Tread measured on every tire, at the most worn point
- Pressure set cold to the value on the door placard
- Winter, all-weather, or M+S tires on all four wheels where your routes need them
- Chains or approved traction devices that fit this tire size, for the drive wheels, stored on board
- Drivers have practiced fitting them in the lot, in daylight
- Studded tires mounted only inside your state’s legal dates
- Spare tire inflated, with the jack and a tire repair kit on board
| Standard | Minimum tread | Applies to |
|---|---|---|
| Colorado traction law | 3/16 inch | Four-wheel or all-wheel drive vehicles relying on their tires during a traction law |
| Wisconsin DHS 105.39 | 1/8 inch at the point of greatest wear | Specialized medical vehicles, checked at least every 7 days |
| 49 CFR 393.75 | 4/32 inch on front tires of buses and trucks, 2/32 inch elsewhere | Commercial motor vehicles |
Colorado’s FAQ adds that mounting only two winter tires weakens their effect, which is why the checklist says all four. Use a tire gauge rather than relying on the dashboard light. The fuel economy site points out that tire pressure drops as the air gets colder, and the federal standard for tire pressure monitors only requires the warning light once a tire is 25 percent below the recommended cold pressure (FMVSS No. 138).
Chain and traction laws on snowy routes
Chain rules are set state by state, and they change the day a storm arrives. These are four examples; check your own state’s transportation department before the season.
| State | Rule | Where it comes from |
|---|---|---|
| Colorado | During a traction law, a vehicle needs four-wheel or all-wheel drive with M+S, mountain-snowflake, or all-weather-rated tires at 3/16 inch of tread, or chains or an approved alternative traction device. A two-wheel-drive van complies only with chains or an approved device. During a chain law, every vehicle needs chains or an approved device. CDOT can put either law on any state highway. Fines run $100 plus a $33 surcharge, or $500 plus $157 if the violation leads to a lane closure. The State Patrol enforces both laws as secondary offenses, citing a noncompliant driver who crashes or holds up traffic. | CDOT, CDOT FAQ |
| California | R-1: chains on everything except passenger vehicles and light trucks under 6,000 pounds gross weight with snow tires on at least two drive wheels, and those must still carry chains. R-2: chains or traction devices on everything except four-wheel or all-wheel drive vehicles with snow-tread tires on all four wheels, which must carry devices. R-3: chains or devices on every vehicle. The speed limit with chains is 25 or 30 miles per hour. | Caltrans |
| Washington | Tires with metal studs are illegal from April 1 to November 1 unless the state transportation department sets extra dates. Chains, traction devices, and studs are allowed when snow or ice makes them necessary. | RCW 46.37.420 |
| Oregon | Medicaid NEMT vehicles must carry tire traction devices when conditions make them appropriate, as part of the required safety equipment. | OAR 410-141-3925 |
Two practical points from Caltrans: chains go on the drive wheels, so drivers need to know whether the van is front- or rear-wheel drive, and the vehicle maker’s specifications say which chains or traction devices the van can take. Confirm your van’s weight rating before counting on California’s R-1 exception, since it stops at 6,000 pounds.
Part 2: lifts, ramps, and boarding in ice
- Snow and ice cleared from the platform or ramp, the doorway threshold, and the door track before deploying
- Landing spot chosen where the ground is clear, or sand or cat litter spread where the platform meets the ground
- Engine running while the lift operates, as the lift manual directs
- Manual backup handle on board, because a battery weakened by cold can leave the lift without power
- Antiskid surface intact; worn antiskid replaced
- Salt and grit washed off the platform with mild detergent and water, then lubricated as the manual says
- Slush dried from the floor at each wheelchair station before a chair is secured
- Ice and grit cleared from the tiedown tracks so the fittings lock in
- Lifts that see heavy winter use booked for service early
Federal rules require lift platforms, ramps, and securement floor areas to be slip resistant (49 CFR 38.23 and 38.25), and a platform glazed with ice no longer is. FTA’s ADA guidance treats clearing snow from ramps and accessible routes as part of keeping accessible features usable, and a van’s platform deserves the same care. BraunAbility’s Century 2 operator’s manual says harsh weather may call for more frequent maintenance and sets the engine running as a condition of operating the lift, and its Millennium 2 manual warns operators to take care in snow and ice and limits cleaning to mild detergent and water. The rest of the daily lift routine is in the wheelchair lift inspection checklist.
Part 3: the daily winter pre-trip
- Roof, windows, mirrors, and lights cleared of snow and ice before the van leaves the lot
- Exhaust pipe free of snow before the engine idles
- Windshield fully clear from the defroster, not just a peephole
- Washer fluid sprays and does not freeze on the glass
- Tire pressures checked with a gauge after a cold night
- Fuel tank close to full
- Heat reaching the back of the van before the first rider boards
- Phone charged, with a car charger on board
- Stranded-rider kit in place (Part 4)
The National Weather Service tells drivers to clear the whole vehicle of ice and snow before a trip, because snow flying off cars causes crashes, and to carry a charged phone and a charger. CDC recommends keeping the tank near full so ice does not form in the tank and fuel lines. On warm-ups, the same federal site advises keeping idling to a minimum; idle only as long as it takes to clear the glass and start the heat toward the rear.
Part 4: the stranded-rider kit
Load it in the fall and check it monthly. The core list follows CDC’s emergency car kit; the NEMT additions account for riders who may be older, less mobile, or dressed for a short ride.
| Item | Why it is there | Named in |
|---|---|---|
| Blankets (at least one, better one per rider seat) | Riders are often dressed for a heated van, not a long wait | CDC kit; Minnesota requires a blanket at all times |
| Ice scraper and snow brush | Clearing glass and the lift area | CDC kit; Minnesota requires a scraper October 1 to April 30 |
| Shovel, plus sand or cat litter | Digging out, and grip for tires and the lift landing | CDC kit |
| Chains or traction devices | Required by law on some routes | CDC kit; Oregon Medicaid rule |
| Jumper cables | Cold batteries fail | CDC kit |
| Flashlight and battery radio, with spare batteries | Light and news when the van is dark | CDC kit; flashlight required in Minnesota, Oregon, and Wisconsin |
| Water and snacks | A long wait for a tow | CDC kit |
| First aid kit | Required on NEMT vans anyway | CDC kit; state and broker equipment rules |
| Portable phone charger | Keeping contact with dispatch | CDC kit |
| Reflectors or flares, and a bright cloth or flag | Being seen by traffic and rescuers | CDC kit; NWS |
| Compressed air with tire sealant | A slow leak far from help | CDC kit |
| Extra hats, gloves, and warm layers | For riders and the driver | CDC kit |
Riders on oxygen or with a fixed dialysis chair time may not be able to wait out a long delay, so a stuck van with one of them aboard needs dispatch involved at once. The full onboard equipment list is in the vehicle safety equipment checklist.
If the van gets stuck with riders on board
- Phone dispatch, then 911 if any rider is medically at risk or the van is stopped somewhere unsafe.
- Stay with the van. The National Weather Service warns that people who leave their vehicle in wind-driven snow become disoriented quickly.
- Run the heat in bursts. NWS advice is roughly 10 minutes of engine time per hour, with a window cracked while the engine runs and the tailpipe kept clear of snow, which guards against carbon monoxide.
- Be visible. Switch the dome light on after dark while the engine is running, tie a bright cloth to the antenna or a door, and raise the hood once the snow stops falling.
- Watch every rider. CDC lists older adults with too little clothing or heat among the people most at risk of hypothermia. Its warning signs in adults are shivering, exhaustion, confusion, fumbling hands, memory loss, slurred speech, and drowsiness. A body temperature below 95 degrees is a medical emergency.
- Warm the core. CDC’s steps are to remove wet clothing and warm the center of the body first (chest, neck, head, and groin), with an electric blanket if one is available or skin-to-skin contact under loose, dry layers of blankets or clothing. Warm drinks help if they contain no alcohol; never try to give drinks to someone who is unconscious.
For breakdowns in any season, the guide to a NEMT vehicle breakdown covers moving riders to a backup van and notifying the broker.
Running winter days with HealthRide
On a snow day, one announcement in HealthRide’s team chat reaches every driver at once, and the live map shows where each van is. Drivers check their vans in the app at the start of each shift, so a problem found in the cold lot reaches dispatch before the first pickup, and riders can follow their driver live from a text link.
Frequently asked questions
- Do NEMT vans legally need snow tires?
- No federal rule requires them, but states set traction rules for snowy roads. In Colorado, when a traction law is on, a vehicle needs four-wheel or all-wheel drive with M+S, mountain-snowflake, or all-weather tires at 3/16 inch of tread, or else chains or an approved traction device. Oregon's Medicaid rule requires NEMT vehicles to carry tire traction devices when conditions make them appropriate.
- How much tread should a van have going into winter?
- More than the legal floor. Colorado's traction law looks for 3/16 inch on every tire. Wisconsin requires 1/8 inch at the most worn point on specialized medical vehicles all year. The federal floor for commercial motor vehicles is 2/32 inch, or 4/32 inch on the front tires of buses and trucks. Measure every tire in the fall and replace any that will not last the season.
- When are studded tires legal?
- State law sets the dates. In Washington, metal studs are illegal from April 1 to November 1 unless the state transportation department extends the season, so studded tires are legal from November 1 through March 31. Check your own state's dates before you mount them, and remember that studs are banned outright in some places.
- Should drivers let the van idle to warm up before the first pickup?
- Only long enough to clear every window and get heat moving to the back. The federal fuel economy site notes that most automakers advise pulling away gently after roughly 30 seconds, since a driven engine warms up faster than an idling one. Riders still need a warm cabin: Virginia's fee-for-service standards take the heat reading from the back of the van, and it has to reach 74 degrees.
- What does a driver do when the van is stuck in snow with riders on board?
- Phone dispatch first, and 911 as well if a rider is medically at risk or the van is stopped somewhere unsafe. The National Weather Service says to stay with the vehicle, give the engine about 10 minutes of run time per hour for warmth, keep a window cracked while it runs, and keep snow off the exhaust pipe. Watch riders for signs of hypothermia, such as shivering, confusion, slurred speech, and drowsiness.
- Does cold weather affect wheelchair lifts?
- Yes, in a few ways. Ice on the platform or ramp is a slipping hazard, a cold battery can leave the lift short of power, and road salt and grit wear moving parts. BraunAbility's Century 2 manual says lifts exposed to harsh weather may need service more often than its 750-cycle schedule, and its Millennium 2 manual warns operators to take care using the lift in snow and ice.
- What winter equipment does Minnesota require?
- Minnesota's special transportation service rules require a blanket in every vehicle all year, plus an ice scraper between October 1 and April 30. The same rule lists a charged fire extinguisher, first aid kit, body fluids cleanup kit, flashlight, and three warning triangles. Your own state and brokers may require more, so check their lists.
