SINGAPORE - Motorists travelling to Malaysia have not been able to register their vehicles for the Vehicle Entry Permit (VEP) on the Road Transport Department (RTD) website.

Unregistered motor vehicles may continue to enter Malaysia, a pop-up message on the website said. The message also said that the "activation of VEP Registration will resume in due course".

The VEP system has been activated at the two land entry points in Johor at the Causeway and at the Second Link since June 1.

The scheme requires Singapore-registered vehicles to register with Malaysia's Road Transport Department before entering.

Users are charged a one-time fee of RM10 (S$3.30) to install a radio frequency identification (RFID) electronic chip which is valid for five years. A total of 144,000 vehicles had registered for the VEP as of July this year.

Singapore-registered vehicles entering Malaysia are also paying a RM20 (S$6.60) levy, called a road charge, which came into effect on Nov 1.

Malaysian Transport Minister Liow Tiong Lai said the VEP would eventually apply to the other 10 road entry checkpoints into Malaysia, from Thailand, Brunei and Indonesia.

Singapore-registered vehicles which are not registered with a VEP, will be refused entry into the country once the system is fully implemented.
