Road Hump

Road Hump signs appear in residential areas, near schools, and in zones requiring speed reduction for safety.

Common throughout Dublin suburbs including Rathgar, Rathmines, and Drumcondra, residential areas in Cork, Galway, and Limerick, approaches to schools nationwide, housing estates built after 1990s traffic calming requirements, and village centers throughout Ireland.

Multiple humps often exist in series on a single road.

The sign typically indicates the first hump in a sequence.

Speed humps ahead require you to reduce speed to 20-30 km/h to avoid vehicle damage and passenger discomfort.

These traffic calming devices are installed to enforce lower speeds in areas with pedestrian activity.

Approach each hump at reduced speed—avoid braking on the hump itself.

Where multiple humps exist, maintain steady low speed rather than accelerating between them.

Emergency vehicles with lights and sirens may traverse humps faster, so yield space for them. Cyclists often move to the road center to avoid humps.

Excessive speed over humps causing loss of control constitutes careless driving: 2 penalty points and fines to €2,000.

Speed humps are typically located in 30 km/h or 50 km/h zones where speed enforcement is strict.

Traveling at the general speed limit (e.g., 50 km/h) through hump zones without reduction results in speeding fines: 3 penalty points and €80-€160 depending on excess.

Dangerous driving due to excessive speed over humps carries 5 penalty points, fines to €5,000, and disqualification.

Speed hump response demonstrates your ability to read road conditions and adapt speed appropriately.

Theory test questions cover the purpose of traffic calming measures and required driver responses.

Practical tests in residential areas frequently include speed humps.

Examiners assess whether you recognize warning signs in advance, reduce speed smoothly to 20-30 km/h, maintain control over the hump without harsh suspension compression, and demonstrate awareness of pedestrians in hump zones.

Approaching humps too fast or braking harshly on the hump results in Grade 2 faults.

Speed causing loss of control results in Grade 3 failure.
