The answer options
- One lane is in use
- All traffic is going one wayCorrect
- This is a single track road
- You cannot stop on this road
Why the other options are wrong
- “One lane is in use” is a distractor. It does not meet the standard the question is testing, which all traffic is going one way does. Picking it in the real test costs a mark you cannot get back, and with a pass mark of 43 out of 50 you only have seven to spare.

Why that is the answer
This rectangular blue sign featuring a white arrow indicates a one-way street. You must be aware that all traffic moves in the same direction, so you will not meet oncoming vehicles. You can use any available lane to position your vehicle according to your destination. This sign relates strictly to traffic flow and direction, not to stopping restrictions, single-track roads, or lane closures.
What road and traffic signs covers
- · Shape and colour rules for orders, warnings and information
- · Regulatory signs including no entry, no waiting and weight limits
- · Warning triangles for bends, junctions, crossings and gradients
- · Road markings: give way lines, hatching, box junctions, edge lines
Mistakes learners repeat on this topic
- · Reading a blue circle as advice rather than a compulsory instruction
- · Confusing the no-entry sign with the no-motor-vehicles sign
- · Assuming hatched areas bordered by a broken line may never be entered
- · Missing that the end-of-restriction sign returns you to the national limit, not to 30
Instructor tip: Answer from the shape first, then check the pictogram — it stops you second-guessing on the look-alike pairs.
How this comes up in the real test
Questions from road and traffic signs appear throughout the 50-question multiple-choice section, and the wording changes between versions. Learn the rule rather than the sentence: the DVSA can ask the same point from the opposite direction, and a memorised answer falls over the moment the phrasing moves.
The pass mark is 43 out of 50, so seven wrong answers is your entire margin. If a whole category is shaky, run the topic practice below until you are getting every question right for the right reason, then go back to full mocks under the clock.
