LGV Driving in Adverse Weather Conditions 3

Question 1

In which situation are drum brakes most likely to suffer fade on an LGV?

Accepted Answer

After the vehicle has driven through deep standing water

Answer

Sustained use on a long downhill gradient only

Answer

In very cold temperatures below freezing

Answer

During normal braking in light rain

Question 2

Why should an LGV driver still exercise extra caution on a recently gritted road?

Accepted Answer

Grit reduces but does not eliminate the risk of ice

Answer

Grit increases stopping distances for heavy vehicles

Answer

Gritted roads attract more traffic and increase collision risk

Answer

Grit can puncture tyres at motorway speeds

Question 3

How does driving in dense fog typically affect an LGV driver's perception of speed and distance?

Accepted Answer

Objects appear closer and speed feels slower than it actually is

Answer

It has no significant effect on perception

Answer

Objects appear further away, causing drivers to travel too fast

Answer

Speed feels faster than it actually is, causing drivers to brake too early

Question 4

What additional hazard does an LGV face when braking hard on a road surface with patches of ice?

Accepted Answer

Trailer swing or jackknifing as wheels lock on different surfaces

Answer

Increased fuel consumption due to wheel spin

Answer

Overheating of the engine cooling system

Answer

Tyre blowouts caused by rapid deceleration forces

Question 5

Which combination of actions best describes safe LGV driving in heavy snow?

Accepted Answer

Drive slowly, use low gears, and allow greatly increased stopping distances

Answer

Drive at normal speed but stay in higher gears to maintain momentum

Answer

Avoid using gears and rely solely on the brakes for speed control

Answer

Use cruise control to maintain a steady speed and prevent wheel spin

Question 6

What does the Highway Code primarily advise for LGV drivers considering a journey in severe icy or snowy weather?

Accepted Answer

Only travel if the journey is essential

Answer

Avoid motorways and use A-roads instead

Answer

Travel at exactly half the posted speed limit

Answer

Keep to main roads and gritted routes only

Question 7

What is the main purpose of using engine braking in low gears when descending a steep hill in icy conditions?

Accepted Answer

To reduce reliance on service brakes and maintain steady controlled speed

Answer

To improve fuel economy during the descent

Answer

To prevent brake overheating by substituting engine braking for friction brakes only

Answer

To increase vehicle speed for a safer, more controlled descent
