Penalties & Legal Consequences

Poor positioning at right-side narrowing can cause collisions with roadside obstacles or departure from the carriageway.

Such incidents constitute careless driving: 2 penalty points and fines to €2,000.

If incorrect positioning causes head-on collision with oncoming traffic also adjusting for narrowing, liability is shared but penalties are severe: dangerous driving charges carrying 5 penalty points, fines to €5,000, imprisonment, and disqualification.

Striking barriers or walls due to inadequate clearance results in full driver liability for damages.

Appears in Driving Test?

Recognizing and responding to asymmetrical road narrowing demonstrates advanced observation skills.

Theory questions test understanding of how single-sided narrowing affects positioning and interaction with other traffic.

Practical tests assess whether you identify the warning early, adjust position smoothly to the left while maintaining safe clearance from oncoming vehicles, and demonstrate awareness that oncoming traffic may also adjust position.

Overcompensating left into the path of oncoming traffic results in Grade 3 failure.

Insufficient adjustment allowing right wheels to leave the carriageway results in Grade 2 faults minimum.
