The Road Safety Authority (RSA), is asking road users to exercise caution during the hot spell.
In particular, the RSA is advising road users to be aware of the dangers posed by “sun glare”, particularly at junctions and road crossings.
This can result in the intensity and brightness of the sun temporarily dazzling or blinding drivers.
It is also advising road users to ensure they have enough water, ensure drivers’ windscreens have been cleared of grease or grime, and to watch out for vulnerable road users.
