What bothers me is that queue jumping itself is not a traffic offence, except where there are double white lines. Traffic along the route to the checkpoint is usually heavy during weekends. There are double white lines only in the final stretch of the viaduct, but the queue could stretch more than 1km back along the Bukit Timah Expressway.

Patient, rule-abiding drivers join the queue at the start of the viaduct. However, along the two-lane viaduct, inconsiderate drivers use the usually empty motorcycle lane on the left to cut into the vehicle lane on the right. Side swiping of vehicles occurs frequently when queue jumpers force their way into the vehicle lane before the double white lines.

The sad thing is that queue jumpers are not penalised because the two lanes are separated by a single white line, and crossing this is not an offence. To add insult to injury, the driver in the vehicle lane usually has to shoulder half the blame in such accidents and ends up paying for the queue jumper's repairs and losing his no-claims bonus.

One way to rectify this injustice is to have double white lines from the start of the two-lane viaduct, so there is no excuse for insurers to blame rule-abiding drivers for queue-jumping accidents.
