Free CDE Traffic Laws & Regulations Questions and Answers

Question 1

What is the legal blood alcohol concentration (BAC) limit for most drivers?

Accepted Answer

0.08%

Answer

In most jurisdictions, including the United States, the legal blood alcohol concentration (BAC) limit for drivers aged 21 and over is 0.08%. Driving with a BAC at or above this limit is considered illegal because it significantly impairs a driver's judgment, coordination, and reaction time, increasing the risk of accidents.

Question 2

When is it permissible to pass another vehicle on the right?

Accepted Answer

When the vehicle ahead is turning left

Answer

Passing on the right is generally restricted for safety reasons, but it is permissible under specific conditions. One such condition is when the vehicle ahead is making a left turn and there is sufficient clear space on the right to pass safely without leaving the paved roadway, ensuring traffic flow continues.

Question 3

What should a driver do at a flashing red traffic light?

Accepted Answer

Stop completely, then proceed when safe

Answer

A flashing red traffic light should always be treated like a stop sign. Drivers must come to a complete stop before the intersection or stop line, and then proceed only when the way is clear and it is safe to do so, yielding to any cross traffic or pedestrians, ensuring intersection safety.

Question 4

What is the meaning of a solid yellow line on your side of the road?

Accepted Answer

Passing prohibited

Answer

A solid yellow line on your side of the road indicates that passing is strictly prohibited for traffic on that side. This road marking is used in areas where it is unsafe to pass, such as near intersections, hills, or curves, to prevent head-on collisions and ensure driver safety.

Question 5

When must a driver yield the right of way?

Accepted Answer

When merging onto a highway

Answer

When merging onto a highway, drivers are typically required to yield the right of way to traffic already on the main road. This ensures a smooth and safe transition into the flow of high-speed traffic, preventing collisions and maintaining the continuous flow of vehicles on the highway.
