Gardaí have appealed to motorists to take care on the roads over the bank holiday weekend.

Checkpoints will be mounted across the country to ensure drivers are complying with the law.

All road users are being urged to be extra vigilant with more cold weather predicted over the next few days.

Gardaí say they will be targeting all traffic offences, including drink-driving, speeding, using a mobile phone while driving and seat belt compliance.

There have been 48 deaths on Irish roads so far this year and gardaí hope the campaign in place over the coming days will play a role in reducing such deaths.

The Wicklow mountain rescue service has asked motorists to avoid the Sally Gap until further notice.

It said snow and ice are making driving conditions difficult and two motorists were stranded yesterday.

Meanwhile, the Dublin Airport Authority expects 210,000 people to travel through the airport over the coming days.

Iarnród Éireann says 200,000 passengers will travel on its InterCity services.

Bus Éireann is also expecting a busy weekend, with thousands of passengers expected to use its services between today and Tuesday.
