When merging onto an interstate, find a safe gap, signal, and speed up to match traffic. Merge only when it’s safe, and don’t assume others will move for you.

If visibility is poor due to darkness or weather, give yourself more space behind the vehicle in front of you. This extra distance gives you more time to react if something happens unexpectedly.

Large trucks take much longer to stop than smaller vehicles. A truck traveling at 55 mph needs about 800 feet to stop, while a car needs about 400 feet.

This sign is displayed on slow-moving vehicles.

An eight-sided sign always signals a stop. You must fully stop at the stop line; if none, stop before the crosswalk. If there’s no crosswalk, stop at a point where you can see oncoming traffic safely.

When turning left, you must yield to oncoming traffic and pedestrians. Complete the turn only when it’s safe and traffic signals permit.
