According to NRS 484D.515, traction devices, tire chains or snow tires must be used in any vehicle when passing by places with a mark or post requiring it. These places are often in the nearby mountain areas. The most popular one employing such rules every winter is Mount Charleston. This tourism area in northwest Las Vegas is noted for its hiking trails and ski areas.
The law obliges a person's motor vehicle or combination of vehicles to comply with using traction devices, tire chains or snow tires before passing by the marked highway, whether it is an emergency or not. Particular highways in the Las Vegas areas are only marked during icy or snowy conditions. Traffic enforcers regulate the passage of motor vehicles in such areas to check if they comply with the requirements.
According to NRS 484D.520, when using traction devices, tire chains or snow tires under certain circumstances, they must comply with the specific requirements applicable to the kind of vehicle they use. The marked highways readily provide the information every motorist needs. These requirements must be followed under specific circumstances. Traction device, tire chains or snow tires must be used for motor vehicles with gross weight or combined gross weight of 10,000 pounds or less. Tire chains must be used for motor vehicles with gross weight or combined gross weight of more than 10,000 pounds. Tire chains and traction devices must be used on all types of vehicles that are not 4-wheel drive and with no snow tires on all wheels.
According to NRS 484D.52, a motor vehicle required to use traction devices, tire chains or snow tires must have them properly installed on at least two driving wheels of the vehicle. They must also be installed on two braking wheels of any trailing vehicle in a combination of vehicles, in cases that the trailing vehicle is equipped with brakes or is required to be equipped with brakes.
