Before beginning a right turn, use the appropriate signal to give surrounding drivers adequate notice of your intentions. Slow down and approach the intersection from the right lane, staying as close as is practical to the right curb or edge of the roadway.

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.

It is illegal to stop, stand, or park in a space reserved for disabled persons unless the vehicle has plates or a permit for such spaces and the person who is named on the plates or permit is in the vehicle.

White lines separate lanes of traffic that are moving in the same direction. Dashed white lines may be crossed to pass or change lanes, if it is safe to do so.

If you are being tailgated by another driver and there is a right lane, move over to the right. If there is no right lane, wait until the road ahead is clear and then reduce your speed slowly. This will encourage the tailgater to drive around you. Never slow down abruptly as this will only increase the risk of your vehicle being hit from behind.

Any time you come to a place where people may cross or enter your path, or where one line of traffic meets another, you should look to the left and right sides of your vehicle to make sure no one is coming.

This sign warns that the road is slippery when wet.

You must drive more slowly than usual when there is heavy traffic or bad weather. However, if you block the normal and reasonable movement of traffic by driving too slowly, you may be cited.

Under New York State law, a BAC of 0.08 percent or higher is evidence of intoxication. A BAC of 0.05 percent or higher is legal evidence of impairment.

A five-ounce glass of wine (12 percent alcohol), a 12-ounce can or bottle of beer, and 1.5 ounces of 86-proof liquor all contain approximately the same amount of alcohol. A person's ability to drive will be equally impaired by the same amount of alcohol no matter what kind of alcoholic beverage they drink.

An octagonal shape is used only for stop signs. All eight-sided signs tell drivers to come to a complete stop before proceeding.

Alcohol reduces reaction time, reduces your ability to see clearly, changes your judgment of speed and distances, often makes you less inhibited, and makes you more prone to take chances. It is especially dangerous to drink and drive after dark because alcohol reduces your ability to recover from the glare of headlights.

Every time you want to change lanes or otherwise move your vehicle to the right or left, signal to alert other drivers to your intentions. Always check your mirrors and turn your head to check your blind spot before attempting any lateral move.

Warning signs are normally diamond-shaped and yellow, although orange warning signs are used in work areas. Such signs warn that you are approaching a hazardous location or an area where special rules apply.

Drivers must yield the right-of-way to pedestrians who are crossing the street in any marked or unmarked crosswalk. In the interest of safety, drivers should yield the right-of-way to people crossing any street.

Legal medications, both prescription and over-the-counter, can impair your ability to drive. They can be particularly dangerous when used in combination with alcohol.

This sign warns drivers that the divided highway ends ahead.

Traffic lanes moving in the same direction are separated by broken white lines. You may cross over dashed lines to pass, if it is safe to do so.

When driving under snowy or icy conditions, you should make speed and directional changes gradually. Never use cruise control when driving on snow or ice because your tires may lose contact with the road and you will lose control of your vehicle.

Because traffic conditions are always changing, you should consistently scan the road ahead. Keep your eyes moving, notice what is happening at the sides of the road, and check behind you every few seconds by using your mirrors.
