You must not use front or rear fog lights unless visibility is seriously reduced to 100 metres (328 feet) or less.

Answer: Answer

Answer

True
The Highway Code explicitly states that drivers must not use front or rear fog lights unless visibility is seriously reduced to 100 metres (328 feet) or less. Drivers must switch them off when visibility improves.

Step-by-Step Solution

1
Identify the statutory visibility threshold defined in the Highway Code for operating vehicle fog lights.
The Highway Code defines seriously reduced visibility as 100 metres (328 feet) or less.
Fog lights produce an intense beam designed specifically to penetrate thick fog and heavy spray.
2
Determine whether fog lights are legally permitted when visibility exceeds this threshold.
Fog lights must not be used when visibility is greater than 100 metres.
Using fog lights in clearer conditions dazzles oncoming drivers and obscures rear brake lights from vehicles behind.
3
Evaluate the accuracy of the statement.
The statement correctly describes the legal requirement.
Drivers are legally mandated to keep fog lights off unless visibility meets the seriously reduced criterion.
