Keep left, overtake right
Singapore traffic keeps left by default. Use the right side for overtaking when it is safe and legal, then move back when appropriate.
Road Rules Basics
Refresh the high-frequency road rules that shape safe driving in Singapore.
These are the rules learners mix up most often: lane position, right of way, bus-lane restrictions, mobile phone use, and alcohol limits.
Give way correctly
Watch for roundabout traffic, pedestrians at crossings, and through traffic when emerging from side roads or filter lanes.
Know bus-lane restrictions
Bus lanes operate during signed hours. Always read the roadside panel because hours vary between normal and full-day bus lanes.
Do not block yellow boxes
Enter only when your exit is clear. Yellow boxes are designed to keep junctions moving, not as waiting spaces.
Wear seat belts and secure children
Seat belts and suitable child restraints are core safety requirements and appear regularly in learner materials.
No handheld mobile use
Using a mobile communication device while driving can attract serious penalties and demerit points.
Alcohol Limit
35 micrograms breath or 80 milligrams blood
Traffic Police training materials state the legal limit as 35 micrograms of alcohol in 100 millilitres of breath, or 80 milligrams in 100 millilitres of blood.
Lane Discipline
Signal early, keep space, and stay predictable.
Mirror checks, blind-spot checks, and clear signals should happen before lane changes.
Do not weave through traffic just because a faster lane opens briefly.
At junctions and filter lanes, commit only when the path ahead is clearly safe.
Keep Linking Concepts
Revisit the traffic sign library for lane, warning, and regulatory signs that support these rules.
