The A7a sign, officially titled 'Bermas baixas', warns that the road ahead has lower shoulders on the right-hand side. This means the verge or roadside verge is significantly lower than the carriageway, which can be hazardous if you drift off the road.
Upon seeing the A7a sign, you must reduce your speed and increase your vigilance. Be ready to take corrective action if your vehicle begins to stray towards the shoulder, as falling into a low shoulder can cause loss of control. Maintain a safe distance from the edge of the road.
A common exam trap is not understanding the specific action required. Learners might think it's just a general warning, but A7a specifically alerts to the danger of the shoulder being lower than the road. The safest response tested in exams is to reduce speed and be extra cautious, rather than just maintaining speed or thinking it's safe to drive on the shoulder.
While the A7a sign itself doesn't explicitly prohibit overtaking or lane changes, you must exercise extreme caution. If the low shoulder reduces visibility or control, or if traffic conditions require reduced speed, overtaking might be unsafe or prohibited by other rules. Always prioritise safety and reduce speed as indicated by the warning.
The A7a sign specifically warns of low shoulders on the right side of the road. If there were low shoulders on the left, a different sign or additional information would typically be provided. Always pay attention to the specific warning given by the sign's placement and symbol.
