DTT Driving in Adverse Conditions

Question 1

How should you adjust your driving in heavy rain?

Accepted Answer

Reduce speed, increase following distance, use dipped headlights, and be aware of standing water

Answer

Maintain normal speed — modern cars handle rain well

Use full beam to see further ahead in rain

Answer

Only reduce speed on rural roads — urban roads have adequate drainage

Question 2

What is the recommended stopping distance on a wet road compared to a dry road?

Accepted Answer

At least double the dry stopping distance

Answer

10% longer — wet roads have little effect on modern tyres

Answer

50% longer

Answer

The same — ABS compensates for wet conditions

Question 3

How should you drive through a flooded section of road?

Accepted Answer

Drive slowly in first gear, keeping engine revs high to prevent water entering the exhaust

Answer

Drive at speed to create a bow wave that clears water ahead

Answer

Only enter flood water if it is below door height — drive at normal speed

Answer

Never drive through standing water regardless of depth

Question 4

When driving in fog, what lights should you use?

Accepted Answer

Dipped headlights and rear fog lights when visibility is below 100 metres

Sidelights only — headlights reflect off fog

Hazard lights to warn other drivers of the fog

Question 5

What is 'black ice' and why is it particularly dangerous?

Accepted Answer

A thin transparent layer of ice on the road surface — dangerous because it is invisible to drivers

Ice formed only at night on unlit roads

Answer

Ice near black rock surfaces on mountain roads

Question 6

How should you brake on an icy road?

Accepted Answer

Steer to the side of the road and brake hard
