Frequently blinking, having difficulty focusing, or experiencing heavy eyelids are possible warning signs of fatigue. If you are fatigued, it is safest to stop driving and leave the road.

Park in an open area. If there is a fire in your vehicle, the first thing you need to do is leave the road and stop. Park in an open area away from anything that could catch fire, such as plants or other vehicles. Do not pull into a service station.

6 . Driving at a consistent speed for a long period of time could be a sign of distracted driving.

If a vehicle is traveling at inconsistent speeds, it could be an indication that the driver is distracted. Give distracted drivers plenty of space on the road.

7 . Cargo being transported should be checked:

Cargo should be inspected before beginning a trip, within the first 50 miles of the trip, and every three hours or 150 miles traveled thereafter. Cargo should be inspected every time the driver stops to take a break. The driver of a truck transporting cargo is responsible for the cargo being safely secured throughout the trip.
