What does this temporary sign mean for drivers of vehicles over 7.5 tonnes maximum authorised mass?
- A Use either the left-hand or middle lane
- B Use only the left-hand lane
- C Use only the middle lane
- D Use any lane
Why this is the answer
Lanes at roadworks often have weight restrictions to keep larger vehicles in the left-hand lane. The lanes through the roadworks are often narrow and therefore not wide enough for large vehicles to pass each other safely. Always look for restriction signs at roadworks. They're usually placed well in advance to give you time to move safely into the correct lane in good time.
Why the other answers don't fit
- A
- Use either the left-hand or middle lane — Two lanes would defeat the point of the restriction.
- C
- Use only the middle lane — The middle lane is not the one reserved for heavy vehicles.
- D
- Use any lane — Any lane is what the sign is there to prevent.

The licence requires them to appear unaltered, so we cannot reword them and neither can anyone else — that is why you will meet the same wording on other sites.
