Zorluk: KolayFog and Poor Visibility

Match each driving scenario in foggy conditions with the correct driver action required by the Highway Code.

  • Visibility drops below 100 metres (328 feet) in dense fogTurn on front or rear fog lights in addition to dipped headlights
  • Visibility clears and road conditions return to normalSwitch off fog lights to avoid dazzling other road users
  • Waiting in a stationary queue of traffic in fogApply the parking brake and release the footbrake to avoid dazzling drivers behind

Cevap

Dense fog below 100 metres matches using fog lights; clearing visibility matches switching fog lights off; waiting in a stationary queue matches applying the parking brake and releasing the footbrake.
According to the Highway Code, fog lights should be used when visibility falls below 100 metres (Rule 226) and must be switched off once visibility improves (Rule 236). In stationary traffic, drivers should use the parking brake rather than holding the footbrake to prevent brake light glare from dazzling following road users.

Adım Adım Çözüm

1
Identify the legal threshold for using fog lights
Fog lights are permitted when visibility falls to 100 metres (328 feet) or less.
Highway Code Rule 226 states that fog lights should only be used when visibility is seriously reduced.
2
Determine the rule when fog clears
Fog lights must be turned off immediately.
Highway Code Rule 236 mandates turning off fog lights to prevent dazzle and ensure brake lights remain clearly visible.
3
Determine lighting and brake etiquette in stationary queues
Apply the parking brake and take your foot off the brake pedal.
Prolonged exposure to bright brake lights at close range causes glare and discomfort to drivers queued behind.
