A severe gale is blowing across a coastal route, and a dense fog bank has just reduced forward visibility to 70 metres. While approaching a cyclist travelling in your lane, you observe that the oncoming lane is completely clear. To maintain adequate safety margins in this specific hazard combination, which TWO actions MUST you take?
- Turn on your rear fog lights due to the 70-metre visibility, but remain alert to switch them off as soon as the fog thins beyond the 100-metre threshold.Cevap
- Provide a substantially wider lateral gap than a standard car's width during the overtake, anticipating that the severe crosswinds may blow the rider off balance.Cevap
- CRely on the standard two-second separation rule before initiating the overtake, deliberately staying close enough to keep the cyclist visible through the fog.
- DConcentrate your visual scanning entirely on the cyclist's movements to anticipate wind buffeting, momentarily suspending your observation of the road ahead.
Cevap
The correct actions are to use rear fog lights strictly while visibility remains under 100 metres and to provide extraordinary lateral clearance when overtaking the vulnerable cyclist in gale-force winds.
In dense fog where visibility drops below 100 metres, rear fog lights must be used to ensure your vehicle is conspicuous, but they must be switched off once visibility improves to prevent dazzling trailing traffic. Additionally, strong crosswinds can easily blow vulnerable road users like cyclists into a vehicle's path, necessitating significantly more lateral overtaking room than a standard manoeuvre requires.
