If conditions such as road construction or bad weather make the posted speed unsafe, drive under the speed limit.

At four-way stops, traffic from all four directions must stop. The first vehicle to reach the intersection should move forward first. If two vehicles reach the intersection at the same time, the driver on the left yields to the driver on the right.

When approaching an unmarked railroad crossing, slow down and be prepared to stop. Before you cross, be sure that no trains are approaching from either direction on any track.

This sign warns drivers that the divided highway ends ahead.

Do not stop at an accident scene unless you are involved or emergency help has not yet arrived. Keep your attention on your driving and keep moving, watching for people who might be on or near the road. Never drive to the scene of an accident, fire, or other disaster just to look.
