Matters needing attention in windy days

1. Try to avoid the "narrow tube effect" when walking and cycling.

Pay attention to the long and narrow passages between tall buildings when walking or cycling. Because the narrow passage will form a "narrow tube effect", the wind in the passage will increase, which will bring certain danger to pedestrians.

Be careful not to stay in billboards and old trees for a long time.

Some billboards may collapse under the strong wind because they are not installed firmly; However, some ancient trees have died, and the foundation is not firm. In windy weather, they may break, posing a danger to pedestrians.

3. Pay attention to the safety of light vehicles.

Because of its light weight, light vehicles may be lifted by strong winds when driving at high speed. You should put some heavy things on the light car or drive slowly.

Be sure to maintain a safe speed and distance. When the wind is strong, you should turn to the service area or leave expressway in time.

When a large vehicle full of goods is driving at high speed in windy weather, the goods on the vehicle may swing, loosen or even fall off from the vehicle under the action of wind. Therefore, when it is windy, the bus should try to avoid following the cart full of goods, and even if it has to follow, it should pay attention to pulling away.

When driving to a corner, you should slow down to avoid the center of gravity shifting and overturning.

4. Pay attention to cycling as little as possible.

Because in windy weather, tailwind or headwind will not cause too much danger to riding, but once riding in crosswind, it may be blown down by strong wind, causing physical injury.
