DRIVING ON WATER

The video discusses the dangers of aquaplaning, where a car loses contact with the road in wet conditions. A tyre company demonstrates this effect using a smooth tread tyre on a revolving drum. As speed increases, the tyre's grip decreases, making driving dangerous. The company is developing a new tyre to maintain grip at higher speeds. Viewers are advised to replace old tyres to ensure safety.

What is the main risk of driving at high speeds in the rain?

• Better traction

• Higher tire wear

• Loss of contact with the road

• Increased fuel consumption

What happens to a smooth tread tyre when it encounters water on the road?

• It gains more traction

• It aquaplanes over the water

• It stops immediately

• It deflates

During the demonstration, what was used to simulate the aquaplaning effect?

• A dry track

• A wind tunnel

• A revolving drum with water

• A wet road

At what speed does the grip of a smooth tread tyre become negligible?

• 70 miles an hour

• 50 miles an hour

• 30 miles an hour

• 90 miles an hour

What is the advice given regarding old tyres?

• Store them for future use

• Replace them to ensure safety

• Use them only in dry conditions

• Keep using them until they burst
