46. 横風
横風は進行方向に対して横から吹く風で、車両を横へ押したり安定性を損なったりします。強風や突風は特にオートバイ、自転車、キャンピングトレーラー、トレーラー、背の高い車両に危険です。運転者は速度を落とし、ハンドルをしっかり持ち、他の道路利用者との間隔を増やします。橋、開けた道路、大型車を追い越すとき、風よけのある場所から出るときは急な風力変化に特に注意します。
What is a crosswind?
A crosswind is wind that blows across the direction in which a vehicle is travelling and can push it sideways.
Why are crosswinds dangerous when driving?
Strong crosswinds and sudden gusts can affect steering and vehicle stability, particularly at higher speeds or on exposed roads.
Which vehicles are most affected by crosswinds?
Motorcycles, bicycles, caravans, trailers and high-sided vehicles are particularly vulnerable because wind can have a greater effect on their balance or large side surfaces.
How should you drive in strong crosswinds?
Reduce speed, keep a firm but relaxed grip on the steering wheel and allow extra space from other road users. Be prepared to correct the vehicle smoothly when gusts change direction or strength.
Where are crosswinds most dangerous?
Crosswinds can be particularly strong on bridges, exposed roads, open countryside and coastal routes, and when leaving tunnels, cuttings or other sheltered areas.
Why can passing a large vehicle be dangerous in strong wind?
A large vehicle can temporarily shelter you from the wind. When you pass it or leave its shelter, the crosswind can suddenly affect your vehicle again, requiring a smooth steering correction.
