231. ひょう
ひょうは、視界を低下させ、路面を滑りやすくし、突然危険な運転条件を作ります。道路上にたまると氷や小石のようにタイヤグリップを低下させ、大きなひょうはフロントガラスや車体を損傷することもあります。減速し、車間距離を増やし、急な操舵・制動を避け、状況が激しい場合は安全な場所へ停止して通過を待つことを検討します。
Do you have to reduce your speed during hail in Belgium?
Yes. Belgian traffic rules require drivers to adapt their speed to the weather, visibility, road condition and traffic situation. The posted speed limit may therefore be too fast during a hailstorm.
Do you have to use your lights during hail in Belgium?
The prescribed vehicle lights must be used whenever conditions make it impossible to see clearly for approximately 200 metres. This can apply when a severe hailstorm significantly reduces visibility.
Are there special traffic rules specifically for hail in Belgium?
There is no separate driving regime specifically for hail. Drivers must follow the general rules and adapt their driving to the weather and road conditions, including slippery roads and poor visibility caused by hail.
What should you do if hail accumulates on the road in Belgium?
Reduce speed, increase your following distance and avoid sudden steering or braking. Accumulated hail can create a slippery road surface with greatly reduced grip.
Can hail damage affect the safety of a vehicle in Belgium?
Yes. Hail can damage the windscreen, windows, mirrors or lights. If damage affects the driver’s visibility or the safe operation of the vehicle, it should be repaired before continuing to drive when necessary.
