Traffic Signs, Signals and Road Markings
Warning, regulatory and information signs, traffic lights, authorised directions, lane markings, road studs and temporary traffic management.
How to prepare for the DVSA car theory test
Connect each Great Britain rule to a driving decision: read the road, identify who is exposed, preserve time and space, and respond safely before a hazard escalates.
Core concepts
Concept 1
Shape, colour, symbol, text and context combine to communicate warning, prohibition, mandatory action or information.
Exam cue: Read the exact sign before applying a familiar road-layout assumption.
Concept 2
Signals and road markings may impose legal requirements as well as guide position and priority.
Exam cue: Use signs, signals and markings together when selecting lane and speed.
Concept 3
Temporary authorised signs and directions control the current road layout even when permanent markings remain visible.
Exam cue: Slow down when control information is obscured, unusual or apparently conflicting.
Risk pitfalls and guardrails
Confusing a warning with a prohibition.
Guardrail: Do not choose an answer merely because it is technically permitted; check whether it preserves view, control, legal compliance and the safety of others.
Following another vehicle through a light without checking the driver's own signal.
Guardrail: Do not choose an answer merely because it is technically permitted; check whether it preserves view, control, legal compliance and the safety of others.
Ignoring a temporary limit because the permanent sign is still present.
Guardrail: Do not choose an answer merely because it is technically permitted; check whether it preserves view, control, legal compliance and the safety of others.
