2. A warning sign showing two children on a see-saw is posted beside a residential street. What does it mean?
Show answer
Answer D: A play area lies beside the road and children may run out

4. Traffic in your lane is backed up and the paved shoulder looks clear. May you drive along it to get past?
Show answer
Answer C: No, the shoulder is not a travel lane
Passing must be done within the roadway; driving on the shoulder to get around traffic is prohibited and surprises anyone entering from the right.

5. Loose gravel has been swept into the middle of your lane on a downhill bend. Which controls are affected most?
Show answer
Answer D: Steering and braking, since the loose stones roll under the tires
Gravel rolls between rubber and pavement, so the tires can neither turn the vehicle nor slow it as they would on a clean surface.

6. What must a driver be ready to do along the stretch of road where this sign is posted?
Show answer
Answer D: Slow down and stop for a child who steps into the roadway
Children misjudge speed and distance and act without warning, so the driver reduces speed, covers the brake and scans the sidewalks and parked vehicles.

7. How is the yield sign shaped and colored?
Show answer
Answer C: A downward-pointing triangle with a wide red border and a red legend on white
The yield sign is a downward-pointing equilateral triangle with a wide red border and the legend in red on a white background, an outline used for no other message.

8. You are on an entrance ramp joining a busy freeway. What should you do with your speed in the acceleration lane?
Show answer
Answer D: Build it up to about the speed of the traffic you are joining
Merging works when your speed matches the traffic stream, because a large speed difference forces the drivers already on the freeway to brake or swerve.

9. A signal on an entrance ramp changes from red to green and lets one vehicle at a time onto the highway. What should you do?
Show answer
Answer A: Stop on the red and go on the green, one vehicle for each green
A ramp meter spaces vehicles out so they join the highway one at a time instead of arriving as a group, and it is a traffic signal like any other.

10. Which shape is used for the school advance warning sign and the school crossing sign?
Show answer
Answer B: An upward-pointing pentagon
The five-sided pentagon with its point up identifies school signing, so the outline alone tells a driver that children may be present.
