Because of their size, trucks need longer distances to stop than smaller vehicles do.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to an upcoming traffic signal. They should be prepared to respond to a yellow light, red light, and/or cross traffic.

Driving while impaired or intoxicated is a serious traffic safety problem. Safe driving is not possible when you drink alcohol or take other drugs. Driving under the influence is dangerous both to you and to others on the road.

A solid yellow arrow has the same meaning as a yellow traffic light. When approaching a solid yellow arrow, you must reduce your speed and prepare for a red light.

Do not make a U-turn at the crest of a hill, near a curve, or anyplace where you or other drivers cannot see 500 feet away. You should only make a U-turn when it is safe to do so.

Unless posted otherwise, your speed is not reasonable and proper if you drive at speeds faster than 20 mph in a school zone. Drivers should exercise caution when driving in an area with an increased likelihood of children or other pedestrians entering traffic.

Railroad crossings are always dangerous. Drivers should always look and listen for trains approaching from either direction on all railroad tracks. Always follow the directions indicated by signs, signals, and flaggers. Never proceed past a railroad crossing until you are certain it is safe to do so.

This sign indicates that a school crossing is ahead.

This sign indicates that there is merging traffic entering from the right.

Highway markings provide information for drivers. Markings help drivers correctly position their vehicles on roadways, inform drivers of safe passing zones, and warn drivers about upcoming conditions.

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign warns drivers that the road ahead curves to the right and then to the left.

Increase your following distance to at least four seconds when following a motorcycle. If the motorcycle and its rider should fall, you will need extra distance to avoid the obstacle.

This sign warns that the road is slippery when wet.

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.

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.

The slow-moving vehicle symbol is a reflective orange triangle. Expect vehicles using this emblem to be driving at speeds of 25 mph or slower.

If you drink alcohol, even just one drink, your chances of being in a crash are much greater than if you did not drink any alcohol. No one can drink alcohol and drive safely, even if you have been driving for many years.

If you follow too closely and the vehicle in front of you slows or stops suddenly, you may not have enough time to avoid a collision.

Driving more slowly than the flow of traffic can be hazardous. If you are on a two-lane, two-way road and driving so slowly that traffic is backing up behind you, you are required to pull off the road and let the other vehicles pass. Only drive significantly under the speed limit when conditions require it.

Any defect that may affect the safe operation of a vehicle should be corrected as soon as possible. Defects should be corrected before the vehicle is driven.

This sign warns of the presence of a hill ahead.

Unless posted otherwise, your speed is not reasonable and proper if you drive at speeds faster than 30 mph in thickly settled areas or business districts. Drivers should use extra caution when driving in an area with an increased likelihood of pedestrians entering traffic.

Before changing lanes, check your side and rearview mirrors for traffic approaching you from behind. Use your turn signal to let other drivers know you plan to change lanes. Check for other drivers who also may be moving into the same lane.

If a vehicle comes toward you with its high beams on, look away from the headlights and toward the right side of the road until the car has passed. This will keep you from being blinded.

Regulatory signs are white, rectangular signs with black markings. Drivers must obey the instructions posted on all regulatory signs. Where this sign is posted, it is prohibited for drivers to pass one another.
