Driver's License Test Prep
Florida Practice Adverse Conditions

You are driving with your high beams on at night. Within how many feet of an oncoming vehicle does Florida law require you to switch to low beams?

  1. A.
    300 feet
  2. B.
    200 feet
  3. C.
    500 feet Correct
  4. D.
    1,000 feet
The Why

The answer is "500 feet"

Florida draws a bright line at 500 feet for oncoming traffic so approaching drivers are not blinded. Choice A is the figure that applies to a vehicle you are following from behind, and drivers who mix the two rules together settle on the smaller number.

Why the others miss

The traps in the wrong answers

A. 300 feet

300 feet is the following-a-vehicle rule, not the oncoming rule. This answer swaps the follow-behind figure printed one line lower for the oncoming figure asked here.

B. 200 feet

200 feet is a return-to-lane distance for passing, unrelated to high beams. This answer carries the pass-and-return-to-lane number over from the passing chapter into the night-driving rule.

D. 1,000 feet

1,000 feet is the taillight visibility standard, not the high-beam rule. This answer grabs the taillight-visibility figure from the equipment table and pastes it onto the dim-your-lights rule.
