In IDEAL conditions in the city, what is the MINIMUM safe following distance behind the car ahead?
- Two seconds behind it. ✓
- Three seconds behind it.
- Four seconds behind it.
- One second behind it.
Answer: A. Two seconds behind it.
In ideal city conditions, keep at least two seconds of following distance behind the vehicle ahead.
Why this is the answer
The handbook's two-second rule says you need at least two seconds of space in front when weather and road conditions are good. It only asks for more than that in specific situations — three seconds on high-speed roads or behind a large vehicle or motorcycle, and four seconds in bad weather or on uneven or slippery roads. Ideal city conditions don't fall into those situations, so the two-second minimum applies.
Why the other answers are wrong
- B. Three seconds behind it. — Three seconds is the distance the handbook asks for on high-speed roads, or when you follow a large vehicle or motorcycle — not the minimum for ideal city conditions.
- C. Four seconds behind it. — Four seconds is what the handbook calls for in bad weather or on uneven or slippery roads, so it is more than you need in good conditions.
- D. One second behind it. — One second is less than the two seconds of space the handbook says you need at minimum in good weather and road conditions.
Remember it
Count "one thousand and one, one thousand and two" as the car ahead passes a fixed object — if you reach that object at "two," you have the minimum.
