Warning signs that indicate approaching hazards are usually yellow with black lettering or symbols. Warning signs in work zones are orange with black lettering or symbols.

As you prepare to make a right turn, you should get as far to the right side of the road as possible. Do not cut across lanes of traffic to perform any turn.

Flashing red lights are used at dangerous intersections. Treat them like stop signs.

Large vehicles have large blind spots to the rear. If you are behind a large vehicle, it is very likely that the driver does not know you are there. Because of this, if you need to pass behind a large vehicle that is backing up, it is always the safest option to wait for the truck's backup maneuver to finish before you pass.

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 single broken line indicates that drivers may cross from either lane to change lanes. Dashed yellow lines alongside solid yellow lines indicate that passing is permitted from the lane next to the broken line, but not from the lane next to the solid line. Only change lanes when it is safe to do so.

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.

Your blood alcohol content (BAC) depends on how much alcohol you drink, how much time passes between drinks, and your weight. It is not affected by the type of alcoholic beverages you drink, your level of physical fitness, or how well you can "hold your liquor."

You should expect to see bicyclists driving with traffic on the road. You should not be surprised to see a bicyclist using the left lane when turning.

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

Holding a driver license is not a right. It is a privilege that must be earned and maintained.

Rather than stopping (as you would when entering other roads), you must use the merging or acceleration lane to speed up and smoothly merge with fast-moving traffic already on the interstate.

You must always signal before turning or changing lanes. You should keep your wheels straight while waiting to make a left turn. If another vehicle hits you from behind, this ensures that you will not be pushed into oncoming traffic.

This sign indicates that a school crossing is ahead.

Increase your following distance when it is difficult to see due to darkness. Use headlights to increase visibility, following the rules for proper use of high beams and low beams. Avoid looking directly at the headlights of an oncoming vehicle to avoid being blinded by the glare.

Alcohol reduces your reaction time, reduces your ability to see clearly, changes your judgment of speed and distances, reduces your ability to recover from the glare of headlights, and often reduces your inhibitions and makes you more likely to take risks.

When driving on wet roads, drivers should increase their following distance.

You should enter a freeway at or near the speed of traffic, unless the speed of traffic exceeds the legal speed limit.

Regulation signs are normally white rectangles with black lettering or symbols. These signs may give information about various kinds of special rules, including speed limits.

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).
