Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This warning sign indicates that drivers are about to encounter a divided highway.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to potential traffic merging from the right. Drivers should prepare to allow the traffic to merge safely.

This sign indicates that the road ahead becomes a divided highway. Keep to the right of the divider or median.

This sign indicates that left turns are prohibited.

A regulatory sign displaying a red circle with a red slash through the middle indicates that a specific action is prohibited. U-turns are not permitted where this sign is posted.

This sign indicates a merge ahead. It warns that two lanes of traffic moving in the same direction are about to become one.

This sign indicates the presence of a pedestrian crossing. You should watch for people entering a crosswalk or crossing your path. Slow down and be prepared to stop.

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.

This is a speed limit sign. It indicates the maximum legal speed that you may drive on the road where it is posted. At times of rain, snow, ice, or other less-than-ideal conditions, you may have to drive more slowly than the posted limit.

In a situation requiring you to yield the right-of-way, you must also stop if you cannot merge safely into the flow of traffic.

The only way to be sure you will have enough time to react to mistakes made by other drivers is to leave plenty of space between you and the vehicles around you.

On narrow roads, you must allow vehicles traveling in the opposite direction at least one-half of the main-traveled portion of the road. Both vehicles must have adequate space in order for the drivers to safely pass one another.

To complete a turn safely, you should activate your turn signal three to four seconds before your turn.

When driving on a two-lane roadway or undivided highway, you must yield to an emergency vehicle using its lights and/or siren, regardless of the direction from which it is approaching. Immediately drive as near as possible to the right side of the road and stop, taking care not to stop within an intersection.

A person whose license has been suspended or revoked does not have the privilege of being allowed to drive. It is prohibited to operate a motor vehicle without a valid license.

Work zones are often stationary, but they may also be present in the form of moving vehicles striping lines, mowing, or removing snow. Work zones are marked by orange signs with black lettering or symbols. Slow down and pay extra attention when approaching or driving through a work zone.

Unless posted otherwise, the speed limit for passenger vehicles and motorcycles in a residential, school, or business zone is 25 mph.

You must use your headlights whenever you use your windshield wipers as a result of bad weather.

You must yield the right-of-way to any emergency vehicle that is using its siren or flashing lights.

Yellow lines are used in the center of the road to separate lanes of traffic moving in opposite directions.

Keep right when another driver begins to pass you on the left. Check for oncoming traffic and adjust your speed to let the passing vehicle move back into the right lane as easily as possible.

Your physical condition has an important bearing on your ability to drive safely. Drivers should be aware of their physical limitations and only drive if it is safe to do so.

To avoid becoming fatigued while taking a long trip, stop every two hours for a short break. If you become drowsy, pull off the road and park in a safe place to take a nap, or find a room to stay for the night.

Because large vehicles have large blind spots on both sides, you should avoid driving beside a large vehicle for a long period of time. It is safest for you to either drop back or move forward when you find yourself directly next to a large vehicle.

If you are following another vehicle at a railroad crossing, check to make sure you have enough room to get all the way across before you drive onto the tracks. You should never try to pass another vehicle as you approach or cross a railroad crossing. Always check for trains before crossing any railroad tracks.

After stopping for a school bus that has its stop arm extended and its lights flashing, watch for children walking along the side of the road. You should always drive with caution when driving near children.

You should never drive around lowered crossing gates. Always look both ways before turning across train tracks and always obey signs and traffic signals. Trains share the road with motor vehicles and bicyclists.

Keeping a safe following distance will enable you to react to an upcoming problem without the need for a emergency stop, which could cause a driver behind you to crash into the back of your vehicle.

When you see an emergency vehicle using its lights or hear it using its siren, you must immediately pull over to the curb or side of the road and stop.

If their vehicle loses traction on a slippery road, a driver with an Anti-Lock Braking System (ABS) needs to press down hard on the brake pedal, hold it, and steer out of danger. In an emergency situation, the ABS automatically pumps the brakes at a faster rate than the driver could. Removing steady pressure from the brake pedal or pumping the brakes will disengage the ABS.

Unless a posted sign prohibits it, you may turn right or left at a steady green light. When turning, you must yield to other vehicles and pedestrians within the intersection.

In business districts, cities, and towns, U-turns are allowed only at intersections.

Before changing lanes, you should always verify that there are no other vehicles in the lane you want to enter by checking your mirrors and looking over your shoulder in the direction you plan to move. You should signal every time you change lanes.

Factors that can affect braking distance include how fast your vehicle is traveling, the condition of your brakes and tires, and the condition of the pavement.
