The Road Safety Authority (RSA), is asking road users to exercise caution while using the roads from Sunday July 17 to Tuesday July 19 as Met Éireann has issued a weather advisory for high temperatures.

Ireland will experience a hot spell this weekend and into early next week. Daytime temperatures will widely reach the high 20s, possibly exceeding 30°C some locations.

In high temperatures, the RSA is advising road users, particularly drivers, to be aware of the dangers posed by ‘sun glare’.

Sun glare can result in drivers being temporarily dazzled or blinded by the intensity and brightness of the sun.

RSA advice to road users

As clear sunny conditions and high temperatures are forecast over the next number of days, the RSA is advising drivers to:

  • Reduce the risk from sun glare and of being dazzled by wearing sun glasses. Be aware of the dangers of sun glare when travelling east in the mornings and west later in the day;
  • Be prepared and ensure you have adequate supplies of water, any delays to journeys could result in road users being stuck in traffic for a period time in hot conditions. Children and pets are particularly at risk during these hot spells of weather;
  • Ensure your windscreen is clear of grease or grime inside and out. Make sure you have plenty of window washer fluid to clear flies/insects and excess dust from the road when driving;
  • Watch out for vulnerable road users such as pedestrians, cyclists, horse riders and motorcyclists. Slow down and allow extra space when passing.

Advice for pedestrians, cyclists and motorcyclists:

  • Beware of the dangers that sun glare can cause, especially when crossing the road and at junctions;
  • Follow current health messaging around the use of sun block when out walking and cycling;

Impact on road surfaces

According to the RSA, road surface temperatures will rise significantly in the hot weather and surface dressed roads (tar and chips) will be prone to softening of the bitumen.

This will lead to bitumen slicks occurring on more minor roads. Road users are advised to slow down and exercise caution when braking in such situations.
