1. A posted speed limit represents the maximum legal speed under what conditions?
Correct answer: Ideal conditions only
The posted limit is the maximum for ideal conditions. When it rains, snows, or fog rolls in, you must slow down; you can be cited for driving too fast for conditions.

2. When you cannot fully move over for a roadside response vehicle with flashing lights, what must you do?
Correct answer: Reduce speed to a minimum of 10 mph under the posted limit
When moving to a farther lane is not possible, you must drop your speed to a minimum of 10 mph under the posted limit while passing the roadside crew.

3. Roundabouts in Washington are designed for what range of travel speeds?
Correct answer: 15 to 25 mph
Roundabouts are built for speeds between 15 and 25 mph. Slow down as you approach, pick your lane, and yield to traffic already circulating.

4. What is the speed limit in a Washington school zone?
Correct answer: 20 mph
In a school zone the posted maximum is 20 mph, since faster travel sharply raises the chance of a deadly crash involving kids. Signs may spell out when it is in effect.

5. Why do minimum speed limits exist on some Washington roads?
Correct answer: So a slow vehicle does not become a hazard to others
Some roads post minimum speed limits so slow vehicles do not become a hazard to other drivers. You are required to travel at least that fast when conditions allow.

6. When you drive near other vehicles, how much space should you leave between you and the vehicle ahead?
Correct answer: A gap of about two vehicle lengths
Keep a gap of no less than two vehicle lengths between your car and the one ahead. That cushion gives you room to respond to trouble in your path.

7. When you are judging whether you have time to turn in front of oncoming traffic, what is the safest approach?
Correct answer: Give yourself more time than you think you need
Oncoming traffic holds the right-of-way, and its speed is tricky to judge. Allowing yourself extra time is far safer than cutting it close before turning across its path.

8. When you merge onto an interstate, who has the right-of-way?
Correct answer: Drivers already traveling on the interstate
Traffic already traveling the interstate holds the right-of-way. Use the entire on-ramp, your signal, and your mirrors, adjusting speed to slip into a safe gap.

9. Why should you slow down in a work zone even when you see no workers present?
Correct answer: Narrow lanes and rough pavement make it hazardous
Narrow lanes and rough pavement in a work zone create hazards on their own. Always slow down there, whether or not workers are present, and increase your following distance.

10. How should you adjust your following distance when the road is covered with snow?
Correct answer: Increase your following distance and slow down
Snowy roads call for a much larger following distance and dramatically reduced speed. The extra space compensates for longer stopping distances on slick surfaces.

11. In a Washington emergency zone with roadside responders present, what is the maximum speed you may ever drive?
Correct answer: Never faster than 50 mph
Inside an emergency zone your speed may never top 50 mph, and you must either change lanes away from responders or drop to a minimum of 10 mph under the posted limit.

12. Even if you are driving at or below the posted limit, when can you still receive a speeding-related ticket?
Correct answer: When you drive too fast for current road conditions
You are responsible for driving at a safe speed for the conditions. If the road is slippery or visibility is poor, going too fast for conditions can earn a ticket even below the limit.
