HPT Road Conditions 3

Question 1

What hazard is created when a road is resurfaced with loose chippings?

Accepted Answer

Chippings can be thrown up by vehicles and shatter windshields

Answer

Loose road chippings can be thrown up by vehicle tires and cause windshield damage or loss of vehicle control.

Question 2

A road has a 'Soft Verges' sign. What hazard does this indicate?

Accepted Answer

Vehicles that leave the carriageway may sink and lose control on soft ground

Answer

Soft verges can cause a vehicle to sink if it leaves the road, making recovery from drifting off the road much more dangerous.

Question 3

How do bridge surfaces create a special hazard in cold weather?

Accepted Answer

Bridges freeze before the surrounding road because cold air circulates underneath

Answer

Cold air circulates beneath bridges, causing them to lose heat faster than surrounding road surfaces and freeze earlier.

Question 4

What specific hazard does a road with a high crown (raised center) present?

Accepted Answer

Vehicles can be pushed toward the edge of the road, especially in crosswinds

Answer

A highly crowned road can cause vehicles to drift outward toward the road edge, particularly in crosswinds or when braking.

Question 5

You see a sign indicating a 'Ford' (water crossing) ahead. What hazard does this present?

Accepted Answer

Your vehicle may stall or lose control if the water depth is underestimated

Answer

Fords can vary in depth, and miscalculating water depth can cause stalling, brake fade, or loss of control.
