Some regulatory signs prohibit certain actions. These signs are rectangular and white with red and black markings. A red circle and slash on top of a black symbol indicates that the specified action is forbidden.

If your vehicle’s accelerator sticks open, your vehicle will continue to maintain its speed or accelerate, even if you remove your foot from the gas pedal. Turn off the ignition, using care to move the ignition switch only far enough to stop the engine and not engage the steering wheel locking mechanism. Apply your brakes and move off the road to a safe area.

Drivers who drive far slower than the normal flow of traffic are a hazard. They often block those behind them, making other drivers jump from lane to lane. Under ideal driving conditions, driving significantly under the speed limit is against the law.

You may make a right turn on a solid red signal only if there is no sign prohibiting a right turn on red. It is also a violation of the law to make a right turn on red when a steady or flashing walk signal is being displayed for an intersecting crosswalk, even if there are no pedestrians in the crosswalk. You may make the right turn after yielding to pedestrians and cross traffic in or approaching the intersection.

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.

When using a freeway exit ramp, do not slow down until you move onto the exit ramp.

This sign indicates the presence of a pedestrian crossing. Drivers should be cautious when driving where pedestrians may be present.

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.

As speed increases, the chance of a fatality increases. If you are moving faster than 80 miles per hour, you have almost no chance of living through a crash. Driving more slowly than other traffic can also be dangerous because other motorists may become impatient and make dangerous moves to pass you.

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 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 means that it is not safe for drivers to enter the indicated road or driveway from their current direction. If you come across one of these signs, you should immediately turn around and drive a different way.

On slippery roads, you should increase your following distance. It may take more time to stop your vehicle than it would under normal conditions.

This sign warns that deer cross the roadway in the area. You should slow down, be alert, and be ready to stop.

Always stop before entering the roadway from a driveway and yield to any approaching vehicles or crossing pedestrians. The stop should be made before crossing the sidewalk area. Failure to stop is unlawful.

Your horn should be used to warn other drivers or pedestrians in situations where they may not see you. For example, if you think another driver is about to hit you, you should sound your horn.

Before you drive, always fasten your seat belt and make sure all your passengers are using seat belts or child restraints. Studies have shown that if you use seat belts, your chances of being hurt or killed in a traffic crash are greatly reduced. Children age 12 and under should always ride properly restrained in a rear seat. Never put a rear-facing infant restraint in the front seat of a vehicle with a front passenger airbag.

When stopped at an intersection, you should first look to your left, as vehicles coming from the left are closer to you than vehicles coming from the right. Look to your right, then look to your left again, in case there are any vehicles coming from that direction that you did not see at first glance.

Double solid lines indicate that you may not pass or change lanes. You cannot cross the lines unless it is to turn left to enter or exit a highway, to turn into or from a driveway, or to make a U-turn (where permitted).

This sign indicates that the right lane on a multilane roadway ends ahead. Traffic in the right lane must merge left.

You should never start a left turn until you can see that all the lanes you need to cross are clear and that you can safely make the turn.

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.

Your ability to stop is greatly affected by the condition of the road. You need to reduce your speed when road conditions are poor in order to maintain control of your vehicle. You will be at risk if you are driving too quickly on roads that are slippery and you need to stop.

If your vehicle’s right wheels leave the pavement, don't panic. Take your foot off the accelerator and steer parallel to the road. Slow down and ease back onto the roadway by keeping both hands on the steering wheel and steering into the road’s right lane with a small turn of the steering wheel. Check for traffic around you before steering back onto the pavement.

This sign warns that there is a steep hill or downgrade ahead.

Always signal for an appropriate amount of time before making a lane change or exiting a freeway. Before you make any move to the right or left, quickly turn your head and look over your shoulder to see if your blind spot is clear.

This sign indicates where a lane is reserved for the exclusive use of left-turning vehicles from either direction. Such a lane may not be used for passing or for through-traffic.

This sign indicates that the road ahead will turn sharply to the right and then to the left.

Locations where it is unlawful and unsafe to pass another vehicle include hills, curves, intersections, and railroad crossings.

You must approach all railroad crossings with extreme caution and cross only when you know that no train is coming from either direction. If there is a flagger at a crossing, you must obey all of their instructions.

Diamond-shaped signs warn drivers of existing or potential driving hazards. You will usually see these signs in yellow or orange.

It is estimated that drivers make 200 decisions for every mile traveled, making it vital that drivers focus their full attention on the task of driving. Performing any additional task can create a dangerous distraction.

A flashing yellow light at an intersection means "caution." If you approach such a light, slow down, look, and proceed with care.

This sign indicates that the road ahead changes direction at an extreme angle (in this case, to the right). Before you reach such an extreme curve, you should slow down as much as you would when making a turn at an intersection.

If a traffic light at an intersection is not functioning due to a power outage, yield to other drivers in the same manner as you would when approaching a four-way stop. When it is your turn, proceed through the intersection with caution.

This sign indicates that the road ahead turns sharply to the right and then sharply to the left.

Blind spots are areas around your vehicle that you cannot see by using your mirrors. Check your blind spots by turning your head and glancing over your shoulders.

Never make last-minute turns. If you reach an intersection where you wish to turn but you are not in the proper lane to make the turn, drive to the next intersection and then make the turn from the proper lane.

A speed limit is the maximum or minimum legal speed you can travel on a road under ideal conditions. You may drive more slowly than the posted speed, but it is illegal to drive any faster. You must drive more slowly where signs or signs indicate a school zone or work zone speed limit. If conditions such as road construction or bad weather make the posted speed unsafe, drive under the speed limit.

At an intersection of two similar roads without a traffic control device, a driver must yield to a vehicle approaching from the right.
