The Steep Descent (W-105) sign is a warning to drivers that a steep downward slope is approaching on the road. As part of Irish warning signs, which typically have a diamond shape and yellow background, this sign alerts you to reduce speed and increase your observation well in advance. You should be prepared to control your vehicle effectively, potentially yielding or stopping if the situation requires, rather than maintaining your current speed or making sudden decisions.
This warning sign indicates a significant downhill gradient ahead, requiring drivers to adjust speed and prepare for increased braking effort. Mastering road sign meaning is crucial for your Irish Driver Theory Test preparation and safe driving.
Irish warning signs are generally diamond-shaped and use a yellow background with a black symbol or wording. This sign draws attention to steep Descent, so the driver can anticipate the risk before reaching it. In a theory-test context, the correct response is normally to slow down, increase observation, and be ready to yield, stop, or change position if the hazard develops.
Steep Descent warns that this hazard, road layout, or traffic condition may appear ahead. The sign gives drivers time to reduce speed, improve observation, and prepare for a controlled response.
