Speed Limits

Learn the speed-limit numbers that show up again and again in Singapore theory prep.

The safest rule is simple: obey the posted sign first. Where no lower or higher sign is shown, use the standard national limits as your baseline.

Quick Table

Singapore speed-limit summary

Most roads unless otherwise stated

50 km/h

OneMotoring states the default road speed limit is 50 km/h.

Expressways

Usually 80 to 90 km/h

Some stretches are lower, especially where signs or tunnels apply.

School Zones

Follow the posted School Zone sign

OneMotoring notes an all-day Enhanced School Zone change from January 1, 2026.

Silver Zones

30 km/h or 40 km/h where posted

OneMotoring now describes both 30 and 40 km/h Silver Zones.

Heavy vehicles and buses

Check class-specific caps and road signs

Vehicle type can lower the applicable cap even on faster roads.

How To Read It

If there is a speed-limit sign, that sign wins.

If there is no sign, fall back to the standard road category limit.

Slow down even further when weather, visibility, pedestrians, or merging traffic make the signed maximum unsafe.

Cross-Study

Review the Demerit Points guide after this so the limits and consequences stay linked.

Use the traffic sign library to reinforce which signs announce a lower speed environment.
