It is time for a review of the speed limits on most Singapore roads, as the limits now are outdated.

There is a good number of dual or multi-lane carriageways with 60kmh or 70kmh speed limits.

But having one fixed speed limit throughout the day does not make sense.

This speed is extremely low for travel during non-peak hours, especially if the road is wide and devoid of sharp and dangerous bends.

There should be electronic displays to cater for different speed limits at peak and non-peak periods.

I propose that speed limits for non-peak periods be changed to no lower than 80 kmh.

The signs should be changed to reflect the non-peak hour limits. There's no need to show the peak hour limits, as the heavy traffic will self-regulate.
