Question

Difficulty: MediumTrams

You are driving a car carrying a tall load securely fitted to your roof rack. What specific hazard should you check for before travelling along an urban street where trams operate?

  1. A
    Severe skidding caused immediately whenever your tyres cross any dry section of track
  2. Reduced overhead clearance from energized electric power cablesAnswer
  3. C
    A doubling of your thinking distance due to electromagnetic fields from the tramway
  4. D
    A legal requirement to give at least a full car width of clearance when overtaking moving trams

Answer

Reduced overhead clearance from energized electric power cables
According to The Highway Code (Rule 303), overhead electric lines for trams are usually suspended at a height of 5.8 metres (19 feet) above the carriageway, but they can be lower in certain locations. Drivers carrying tall or bulky items on a roof rack must verify that they have sufficient vertical clearance before travelling under overhead wires to prevent severe entanglement and electrical hazards.

Step-by-Step Solution

1
Identify the vehicle condition and environment
The driver is operating a vehicle carrying a tall roof load along a street with an active tram network.
Vehicle dimensions, particularly total vertical height, are significantly altered when carrying bulky rooftop cargo.
2
Recall the infrastructure rules for tram routes under The Highway Code
Tram networks utilize overhead power lines suspended above the carriageway, typically at 5.8 metres (19 feet) but sometimes lower.
The Highway Code Rule 303 instructs drivers of high vehicles or those carrying roof loads to verify adequate height clearance under overhead wires.
3
Select the option that directly addresses the height and infrastructure hazard
Checking for reduced overhead clearance from overhead electric cables is the correct safety precaution.
Failing to account for load height near live overhead tram wires creates severe risk of snagging cables and electrical danger.
