Rules to remember10 key speed limits and stopping distance rulesShow the rules
  1. When two or more lanes go the same direction, slower traffic must move to the right so others can pass. (p. 35)
  2. The handbook lists 25 mph as the speed limit for business and residential areas. (p. 35)
  3. Doubling your speed makes your braking distance about four times as long, not just twice as long. (p. 41)
  4. During the first rain of a season, the mix of oil and water on the pavement is very dangerous. (p. 41)
  5. Most cars begin to lose traction and hydroplane between 35 and 55 mph in heavy rain, so slow down. (p. 41)
  6. Studies show normal driver reaction times are 2 to 2.5 seconds, and they get longer when decisions are complex. (p. 41)
  7. If you reach the fixed point before counting 'one thousand two,' you are following too closely. (p. 42)
  8. At 40 mph or less, stay at least two seconds behind the vehicle ahead; most instructors recommend up to four. (p. 42)
  9. At freeway speeds you need to look ahead at least 20 to 30 seconds so you can react in time. (p. 42)
  10. Look left, right, and left again just before entering an intersection. (p. 42)
