It is much harder to see at night. Using the right beam at the right time lets you see as far as possible without blinding others.

Know the rule

Use your high beams whenever there are no oncoming vehicles. They let you see twice as far as low beams.

High beams are important on unfamiliar roads, in construction areas, and where people may be along the side of the road.

Know the rule

In fog or when snowing or raining hard, high beams reflect back, causing glare and making it harder to see.

Put it into practice

You're on a dark, unfamiliar rural highway with no one around, so you use high beams. When an oncoming car appears about a block away, you dim to low beams.

  2. About one block away
  3. Only once you can see their license plate

Dim your high beams whenever you come within about a one-block distance of an oncoming vehicle.

Handbook p. 21 ↗
Within what distance should you use low beams when following another vehicle?
  1. 1,000 feet
  2. 200 feet
  3. 100 feet
  4. 500 feet

Answer: 200 feet

Use low beams within 200 feet when following another vehicle or in heavy traffic.

Handbook p. 21 ↗
When should you use low beams instead of high beams?
  1. Whenever driving above 45 mph
  2. On unfamiliar roads
  3. Whenever passing another vehicle
  4. In fog, snow, or heavy rain

Answer: In fog, snow, or heavy rain

Use low beams in fog or when it is snowing or raining hard, since high beams reflect back and reduce visibility.

Handbook p. 21 ↗
Is it acceptable to drive at night using only your parking lights?
  1. Yes, if your high beams are broken
  2. Yes, on residential streets
  3. Yes, if you drive slowly
