DTT HGV Road Signs 2 — Questions and Answers
Question 1: What does a sign showing 'CLEARWAY' mean for truck drivers?
- No stopping or parking during the times shown — vehicles must keep the road clear (Correct answer)
- A clear road with no traffic expected
- A road cleared of snow and ice
- Priority for trucks over other vehicles
Correct answer: No stopping or parking during the times shown — vehicles must keep the road clear
A Clearway sign means no stopping or parking is permitted during the hours indicated (or at all times if no hours are shown). This keeps traffic flowing on busy routes. Even loading and unloading may be prohibited during clearway hours.
Question 2: What does a sign showing an upward arrow and a downward arrow (one larger than the other) mean?
- Priority for traffic in the direction of the larger arrow — oncoming traffic must yield (Correct answer)
- Two-way traffic ahead
- One-way street with alternate direction at different times
- Traffic speed information
Correct answer: Priority for traffic in the direction of the larger arrow — oncoming traffic must yield
This sign indicates that traffic in the direction of the larger arrow has priority over oncoming traffic. The traffic facing the smaller arrow must give way. This is commonly seen at narrow bridges and roadworks.
Question 3: What are chevron signs (black and white arrows on a curve) designed to indicate?
- The direction and severity of a sharp bend — they guide drivers through the curve (Correct answer)
- A road junction ahead
- A car park entrance
- The direction to a motorway
Correct answer: The direction and severity of a sharp bend — they guide drivers through the curve
Chevron signs are placed on the outside of sharp bends to warn drivers of the curve's direction and help guide them through it. The number and size of chevrons indicate the severity of the bend. Particularly important for large vehicles with longer braking distances.
Question 4: What does a sign showing 'T' in red on a white background at the end of a road indicate?
- A T-junction ahead where you must give way or stop (Correct answer)
- A turning area for trucks
- A temporary road surface
- A toll road ahead
Correct answer: A T-junction ahead where you must give way or stop
A T-junction ahead sign warns that the road ends and you must turn left or right. You must give way to traffic on the road you are joining. This is particularly important for truck drivers who need more time and space to make the turn.
Question 5: What does a variable message sign (VMS) on a motorway typically display?
- Real-time traffic information such as speed advisories, lane closures, incidents, weather warnings, or journey time estimates (Correct answer)
- Permanent speed limits
- Tourist information
- Radio station frequencies
Correct answer: Real-time traffic information such as speed advisories, lane closures, incidents, weather warnings, or journey time estimates
Variable message signs are electronic displays that show real-time information including advisory speed limits, lane closures, accident warnings, fog warnings, and travel time estimates. Truck drivers must pay attention to these as conditions can change rapidly.
Question 6: What does a sign showing a height restriction of 4.65m indicate for a truck driver?
- The maximum vehicle height (including load) that can safely pass through is 4.65 metres — drivers must know their vehicle's total height (Correct answer)
- The road is 4.65 metres wide
- The bridge is 4.65 metres long
- The speed limit is 4.65 km/h below normal
Correct answer: The maximum vehicle height (including load) that can safely pass through is 4.65 metres — drivers must know their vehicle's total height
This indicates the maximum safe height for passing under a structure. Truck drivers must know their vehicle's exact height including any roof-mounted equipment, containers, or loaded cargo. Bridge strikes cause major disruption and are a criminal offence.
