The Immigration and Checkpoints Authority (ICA) said more than three million travellers crossed the Woodlands and Tuas checkpoints over the Chinese New Year period between Jan 24 and Jan 30, peaking at 521,000 travellers in a single day on Jan 24, reported The Straits Times.

ICA said during peak periods, people travelling by car waited for up to three hours for immigration clearance due to traffic from Malaysia.

The school holiday period in Singapore will run from March 14 to 24 while the Hari Raya Aidilfitri holiday period is from March 28 to April 1.

ICA said travellers should ensure that their passports have a remaining validity of at least six months, and not to bring along prohibited or controlled items.

Those travelling by car and motorcycle are encouraged to use QR codes instead of passports for faster and more convenient immigration clearance, it said.

Motorists are also advised to check the traffic situation at the land checkpoints before embarking on their journey, and to refrain from queue-cutting, which compromises the safety of others on the road.

Errant motorists caught queue-cutting will be turned away and redirected to the end of the line, ICA said.
