Stopping distances increase on wet or icy roads. Stopping distances also increase on road surfaces covered in loose gravel or stones.

License plates must be fastened horizontally at least 12 inches from the ground and in a manner that prevents swinging. They must be clearly visible and kept clean and legible.

You should always slow down when driving on narrow or winding roads, near intersections, near railroad crossings, on hills, in sharp or blind curves, where there are pedestrians or driving hazards, and when the roads are wet or slippery.

This sign indicates that an intersection with a crossing road is ahead.

On a traffic signal arranged vertically, red is always on top and green on the bottom. When arranged horizontally, red is always on the left and green on the right.

When intending to back up, always check behind your vehicle before getting in. Children and small objects are difficult to see from the driver’s seat. While backing, turn your head so you can see through the rear window. Do not depend only on your mirrors or sensors.

Yield the right-of-way to the driver on your right at a four-way intersection if you both arrive to the intersection at the same time. You may then proceed when it is safe to do so.

If there are two railroad tracks next to each other, watch for a second approaching train after one train passes. Do not begin to cross the tracks until you’re sure no train is approaching from either direction on either track.

If an aggressive driver cuts you off on the roadway, stay calm and get out of their way. Trying to get even with an aggressive driver risks escalating the situation and increasing the danger.

Always use the proper turn signal when changing lanes, pulling into or out of a parking space, or pulling into traffic from an alley or parking area. Communicate with other drivers on the road to help prevent accidents.

A solid line along the side of the road indicates where its edge is, marking the boundary between the travel lane and the shoulder. If the edge line angles toward the center of the road, this means that the road is narrower ahead.

You drive defensively when you identify dangerous driving situations and take action before an accident occurs. Defensive driving helps prevent conflicts with aggressive, offensive, discourteous, careless, inattentive, impulsive, ignorant, or intoxicated drivers or pedestrians.

If you approach an emergency vehicle, tow truck, or roadside assistance vehicle that is stopped with its lights flashing, you must change lanes to allow the vehicle extra space. If there is only one lane moving in your direction, or if changing lanes would be unsafe, you must slow down to a speed below the posted speed limit and give the stationary vehicle as much room as possible. Always slow down and be prepared to stop when you approach an emergency scene.

The exhaust system helps remove toxic gases, reduce the noise, and cool the hot gases coming from a running engine. Fumes from a leaky exhaust system can cause death in a very short time. They can also make you drowsy while driving.

Worn or bald tires can increase your stopping distance and make turning more difficult. Tires without adequate tread also increase the risk of hydroplaning.

A double solid yellow line down the center of a two-way road means that it is prohibited for traffic from either direction to cross the center to pass.

This sign warns that the road is slippery when wet.

When you see any signs indicating a nearby railroad crossing, you should slow down, look for a train, and be ready to stop. If the red warning lights are flashing or the gate is down, you must stop 15 to 50 feet before the railroad tracks. Do not try to go around the gate.

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.

When approaching an intersection with a solid yellow traffic light, slow to a stop before entering the intersection, if it is safe to do so. If you can't stop safely, drive carefully through the intersection.

Flashing red lights are used at dangerous intersections. Treat them like stop signs.

Railroad crossings are always dangerous. Drivers should look and listen for an approaching train coming from either direction before proceeding across the tracks. Watch for signals indicating an approaching train and never proceed until you are certain it is safe to do so.

You must stop at a railroad crossing when directed to do so by a flagger, stop sign, or warning devices, such as gates or flashing lights. Not all railroad crossings are equipped with such devices. It is against the law to drive around lowered railroad crossing gates.

A large truck has large blind spots to the front, sides, and rear of the vehicle. Avoid lingering in these areas. Because of their larger size and weight, trucks require more room to maneuver and stop than passenger vehicles.

This sign indicates that there is a railroad crossing on the road ahead. You should always slow down when approaching a railroad crossing. Trains cannot yield to cars, so you must let them pass before crossing the tracks.
