1. How do you know it is safe to pull back in after passing another vehicle?
Correct answer: When both of that vehicle's headlights appear in your rearview mirror
Wait until both of that vehicle's headlights show in your rearview mirror; then there is room to return to the driving lane.

5. How much should you cut your speed when driving on packed snow?
Correct answer: By half
Halve your speed on packed snow, ease off roughly 10 mph on a wet road, and slow to a crawl on ice. Snow tires or chains help when snow is on the road.

6. How does the "three-second rule" tell you whether you are following too closely?
Correct answer: Count three seconds from when the vehicle ahead passes a fixed point until you reach it
Pick a fixed object, watch the back of the car ahead pass it, then count. Reaching the same spot before you finish counting three means you are too close, so drop back and check again.

7. You need to cross several lanes of traffic. What is the recommended way to do it?
Correct answer: Take the lanes one at a time
Move over one lane at a time rather than sweeping across in a single motion, and get a proper gap for each change.

8. How close to a hill or curve is it unsafe to begin passing?
Correct answer: Within one-third of a mile
You need about ten seconds of clear road, roughly a third of a mile. When a hill or curve sits that close, treat the blocked view as though a vehicle were already coming and stay behind.

9. What is the default limit on rural interstate highways in New Mexico?
Correct answer: 75 mph
Rural interstates carry a maximum of 75 mph unless signs say otherwise, and the top figure applies only in ideal conditions.

10. How large a gap do you need in order to merge with other traffic?
Correct answer: About four seconds
Look for about four seconds of space. Slotting into the middle of it leaves both you and the driver now behind you a two-second cushion. Never squeeze into a gap that is too small.

11. What should you do if the posted minimum speed on a road is faster than you want to drive?
Correct answer: Take a different road
Minimum limits exist so slow vehicles do not endanger others. If you cannot comfortably hold that speed, choose a different route.

12. At about 55 mph, how much time do you need to pass another vehicle safely?
Correct answer: About ten seconds
Passing at that speed eats up roughly ten seconds, so you need a ten-second hole in oncoming traffic plus enough sight distance to use it.
