The A7b 'Bermas Baixas' sign is a Portuguese warning sign indicating that the road ahead has low shoulders on the left. This means the paved road surface ends abruptly, and the ground beside it is significantly lower. Drivers should anticipate potential hazards associated with uneven terrain or reduced road width.
When you see the A7b sign, it's crucial to slow down before reaching the hazard. Increase your following distance, improve your overall observation, and be ready to brake or steer if necessary. Maintaining a safe speed and being prepared for potential issues like a slippery surface or loss of control is key.
Yes, you should avoid continuing at your current speed when the hazard warrants earlier braking. Overtaking or changing lanes unnecessarily where the warning implies reduced control or space is also inadvisable. Crucially, do not wait until you are at the hazard point to react; prepare well in advance.
A common trap is simply knowing the name of the sign without understanding the required driving behaviour. Exam questions often test your ability to identify the safest response, which involves slowing down, increasing observation, and being prepared for the specific risks associated with low shoulders, not just recognizing the symbol.
While the A7b sign doesn't explicitly prohibit overtaking or lane changes, you must exercise extreme caution. If the low berms affect road width, visibility, or stability, it would be unsafe and therefore illegal to perform such manoeuvres. Always prioritise safety and adapt your speed and position according to the immediate road conditions indicated by the sign.
