You should maintain at least 200 feet behind a snowplow because blowing snow reduces visibility and sand or salt can damage your windshield.

Maintaining a safe following distance is crucial for defensive driving because it provides the driver with enough time and space to react to sudden stops or hazards created by the vehicle in front. This reaction time is essential for safely applying brakes or maneuvering to avoid a collision. It prevents rear-end collisions and allows for better overall situational awareness.

Large trucks (over 26,000 lbs) are limited to 70 mph on Wyoming rural interstates, which is 10 mph less than the passenger vehicle maximum.

Stop safely nearby, call 911 immediately, and offer first aid only if trained — untrained movement of injured persons can cause additional harm.

Using headlights during daylight hours, especially in conditions like those often found in Wyoming (e.g., snow, fog, or open roads), significantly increases a vehicle's visibility to other drivers. This makes it easier for oncoming traffic or vehicles merging from side roads to spot your car, reducing the risk of collisions. It's a simple yet effective defensive driving technique that enhances overall road safety.

Wyoming allows a maximum speed of 80 mph on most rural interstate highways during the day for passenger vehicles.
