Due to the continuous deterioration in ambient air quality, indicating a high level of fine particulate matter (PM10), the alert procedure has been extended to cover the entire department from Friday, September 08, 2023 at 4pm until Saturday, September 09, 2023 at 4pm.
This episode of pollution is attributed to a combination of meteorological conditions favorable to the accumulation of pollutants in the atmosphere with a dust plume from the Sahara desert releasing a very large amount of particles into the air.
Due to the exceeding of the limits set by French and European regulations and in order to protect the population of Brittany, the Prefect of Île and Vaillant issued an order implementing regulatory measures aimed at reducing the pollution cycle, in addition to health and behavioral recommendations.
The extension of these regulatory measures takes effect from 4pm on Friday 08 September 2023. Therefore, the maximum permitted speed on the entire 2*2 lane road network remains reduced by 20 km/h:
- 130 → 110 km/h (highway)
- 110 → 90 km/h (highways)
This action is displayed on available variable message tags. A speed check will be conducted on the concerned axles. This regulatory measure aimed at reducing the pollution episode is in effect until tomorrow, Saturday 09 September 2023, at 4 pm and can be extended if necessary. If the crisis intensifies in the coming days, new regulatory measures could be put in place, such as a differentiated vehicle trading system.
