The exhaust system carries exhaust gas out of the vehicle and prevents fumes from entering into the passenger compartment. To prevent carbon monoxide poisoning, keep your exhaust system free of leaks. Replace all defective parts immediately.

Entrance ramps for highways often have acceleration lanes. When merging with traffic from an acceleration lane, you should put your signal on, look for an opening in traffic, accelerate up to the speed of traffic, and merge into an opening in traffic.

This sign marks a one-way road, entrance, or exit. If you are facing this sign, traffic is coming toward you. Turn around if you are driving toward this sign.

Even if you are facing a green traffic light, do not start across the intersection if there are other vehicles blocking your way. If you are caught in the intersection when the light changes to red, your vehicle will block cross traffic. You can get a ticket for blocking an intersection.

You may turn right during a red light if no signs prohibit it. When turning on red, come to a complete stop, activate your turn signal, yield to all traffic and pedestrians, and then proceed safely. Any turn should be made from the lane closest to the direction of the turn.

You may not pass another vehicle on a hill or in a curve because you cannot see oncoming traffic and may cause a collision. Never pass another vehicle by driving onto the shoulder of a highway. Passing another vehicle by driving over a solid yellow line is prohibited.

Unless otherwise posted, the maximum speed limit is 15 miles per hour for vehicles driving within a school zone or near a school crossing where children and/or crossing guards are present.

Be prepared to reduce your speed and use caution when directed to do so by a sign, flagger, or law enforcement officer. Failure to do so is illegal and is dangerous to those working in construction zones.

If your vehicle begins to skid, release the accelerator or brake pedal to regain vehicle balance. Steer in the direction of the skid to regain control of the vehicle.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign tells drivers to prepare to allow traffic to safely merge from the right.

This sign indicates that the road may be slippery when wet. Exercise caution when driving on a slippery road.

Warning signs are usually diamond-shaped and yellow with black lettering or symbols. They warn drivers about special situations or potential hazards ahead.

Develop a routine for entering and leaving your car. Before switching on the ignition, buckle your safety belt and see that all passengers do likewise.

If you look into the headlights of an oncoming vehicle, the pupil of your eye will contract. After the oncoming vehicle has passed, there will be an interval of time during which the pupil must readjust to the less intense light. During this recovery period, you are virtually driving blind.

When making a left turn where there is approaching traffic, you must wait for the approaching traffic to go through before you turn. You may enter the intersection to prepare for your left turn if the light is green and no other vehicle ahead of you plans to make a left turn.

Warning signs are usually yellow with black markings. This sign alerts drivers to where pedestrians may be crossing. If a pedestrian is crossing in a crosswalk marked with this sign, drivers must stop and remain stopped until the pedestrian is no longer in the crosswalk.

This sign means that a traffic signal is ahead. You should slow down and be prepared to stop.

This sign indicates that U-turns are prohibited.

A solid yellow arrow means that the protection of a green arrow is ending. If you are turning in the direction of the arrow, you should prepare to stop and yield the right-of-way to oncoming traffic before turning.

This sign indicates parking spaces that are reserved for vehicles displaying Persons with Disabilities license plates, Disabled Veteran license plates, and/or disabled parking placards.

Driving during the first half hour of rainfall is dangerous because roadways become extremely slippery when the water mixes with oil and other chemicals on the road surfaces that have not yet washed away. Use extra caution when driving on slippery roads.

This sign alerts you to the possibility of traffic merging into the main stream of travel. After checking to your side and rear, you should move into another lane, if possible, to allow merging motorists a clear path.

Your vehicle's brake lights indicate to other drivers that you are slowing down or stopping. Your brake lights should always be in working order when you are driving on any roadway.

If you are involved in a crash, move your vehicle off of the road and stop, if possible. If anyone is injured, call 911 and provide appropriate help. You must report the crash to law enforcement if there is an injury, a death, and/or more than $1,000 in property damage (or more than $200 worth of damage made to non-vehicle government property, such as signs or guardrails).

It is not always easy to maintain a safe distance behind your vehicle. However, you can help keep the driver behind you a safe distance away from your vehicle by maintaining a steady speed and signaling turns, lane changes, and deceleration in advance.

A reflective orange triangle on the rear of a vehicle means it travels only at slow speeds. You may see this sign on roadwork equipment, farm vehicles, or horse-drawn wagons and carriages. It appears as a solid orange triangle during the day and a hollow red triangle at night.

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.

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

When traffic control signals are not working, a driver must always treat the intersection as an all-way stop and come to a complete stop, unless otherwise directed by law enforcement. The driver must then look and yield the right-of-way before entering the intersection.

There are a number of locations where it is unlawful to park, including on a crosswalk or in a marked bicycle lane. When parking on the street, you must be within 12 inches of the side of the road.

This sign prohibits drivers from making a U-turn. You cannot turn around to go in the opposite direction at an intersection where this sign is posted.

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign warns drivers that an upcoming bridge may be too narrow to meet or pass a truck and that they should be careful.

At a four-way stop, the vehicle that reaches the intersection first moves forward first. If two or more vehicles arrive at the same time, the vehicle on the right has the right-of-way.

You must report an accident to a law enforcement agency if there is an injury, a death, or damage worth $1,000 or more to any one person’s property. You must also report a crash if there is damage valuing $200 or more made to government property (such as signs and guard rails).

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