Road Signs & Markings
59 practice questions for the BTT & FTT
Most Basic Theory Test questions on signs and markings come down to one skill: reading the road surface and kerb correctly at a glance. In Singapore the colour and pattern of a line tells you a great deal. Yellow lines along the kerb control parking and stopping, white lines in the middle of the road control crossing and overtaking, and zig-zags warn you that something important is just ahead.
The details are where candidates lose marks. A single yellow line restricts parking only during set hours, while double yellow lines and yellow zig-zags apply at all times, and double zig-zags ban even a quick drop-off. Bus lanes come in two flavours with different operating hours, and a yellow box junction has a short list of situations in which you may wait inside it.
Traffic light questions also sit here: what amber really requires, what a flashing amber means, and how red and green arrows interact. Work through these questions until you can explain why each wrong option is wrong, not just pick the right one.

All road signs & markings questions and answers
-
A single unbroken yellow line runs along the kerb beside you. When may you NOT park there?
Show answer
Between 7am and 7pm, except on Sundays and public holidays
A single yellow line is a time-limited restriction: no parking from 7am to 7pm, but it does not apply on Sundays and public holidays. Lines that apply around the clock are doubled or zig-zagged.
-
What do two parallel unbroken yellow lines along the side of the road mean?
Show answer
No parking at any time, but you may stop briefly to pick up or set down passengers
Double yellow lines ban parking at all hours on that side of the road. A brief stop to let someone in or out is still allowed, which is what separates them from double zig-zag lines.
-
You see double yellow zig-zag lines along the kerb. What is the rule?
Show answer
No stopping at any time on that side of the road
Double yellow zig-zags are the strictest kerb marking: you may not stop there at all, even for a moment. Breaking this rule carries demerit points as well as a fine.
-
How does a single yellow zig-zag line differ from double yellow zig-zag lines?
Show answer
A single zig-zag bans parking at all times but still allows an immediate pick-up or drop-off
A single yellow zig-zag means no parking at any time, though you may stop just long enough to let passengers in or out. Doubling the zig-zag removes that allowance and bans stopping altogether.
-
White zig-zag lines are painted along the edge of the road ahead. What do they warn you about?
Show answer
A pedestrian crossing is ahead; do not stop, wait or overtake in the zig-zag area
White zig-zags give advance warning of a pedestrian crossing. Within them you must not stop, wait or overtake, and pedestrians are not supposed to cross on the zig-zag section itself.
-
You are going straight on at a yellow box junction. Your light is green, but traffic beyond the box has stopped. What should you do?
Show answer
Wait behind the stop line until there is room to clear the box completely
Entering a yellow box and causing an obstruction is an offence even on a green light. If your exit is blocked, stay behind the line until you can drive straight through.
-
In which situation may you wait inside a yellow box junction?
Show answer
When you are turning right and are held up only by oncoming traffic
Turning vehicles may wait in the box for a gap in oncoming traffic, or for pedestrians to finish crossing, because they will not block cross traffic. If the light turns red while you wait, complete the turn and clear the box.
-
A lane is marked with a single continuous yellow line (a normal bus lane). When may cars NOT drive in it?
Show answer
Weekdays 7.30am to 9.30am and 5pm to 8pm, excluding weekends and public holidays
A normal bus lane operates on weekday mornings and evenings only. Outside those hours, and wherever the yellow line is broken to let you turn into or out of a side road, other vehicles may use it.
-
How can you tell that a bus lane is a full-day bus lane?
Show answer
A red line runs alongside the yellow line
A red line parallel to the yellow line marks a full-day bus lane. Its restriction runs from 7.30am to 11pm, Monday to Saturday, and does not apply on Sundays and public holidays.
-
Unbroken double white lines run down the centre of a two-way road. Which of these is allowed?
Show answer
Overtaking, provided you stay entirely to the left of the lines
You must never cross double white lines, so right turns and U-turns over them are banned, and parking is prohibited on both sides. You may pass another vehicle only if you can do it without crossing the lines.
-
You are on a side road and reach a pair of broken white lines painted across your lane at the junction. What do they tell you?
Show answer
Give way to traffic on the major road
Parallel broken white lines across the road are a give-way marking. Slow down and let main-road traffic pass, stopping only if you need to. A single solid line across the road, usually with a stop sign, requires a full stop.
-
The traffic lights at a junction are showing a flashing amber light. What does it mean?
Show answer
The signals are faulty; proceed with care and give way to traffic from the right
A flashing amber means the signals are out of order. Treat the junction with extra caution and give way to traffic approaching from your right.
-
You want to turn right. The main signal is green, but a red arrow pointing right is lit, and there is no oncoming traffic. What should you do?
Show answer
Stay behind the stop line until the red arrow goes off
A red arrow means stop for that direction regardless of the other signals. You must wait behind the stop line even if the road ahead looks clear.
-
What does an area of white chevron markings on the road surface mean?
Show answer
It channels traffic, so you must not drive or park on it
Chevron areas guide traffic into the correct paths. They are not lanes or parking spaces, so keep off them.
-
You see diamond-shaped signs with a black symbol on an orange background. What are they?
Show answer
Warning signs for a work zone
Work zone signs are orange with black symbols or text. Diamond-shaped ones warn of a hazard and rectangular ones give information. Obey any temporary speed limit posted in the work zone.
-
You see this sign at a junction. What must you do?
Show answer
Stop before the white line and give way to traffic from both the right and the left
A stop sign needs a full stop at the white line every time, even when the junction looks empty. Move off only after letting traffic from either side go first.
-
What does this sign tell you to do?
Show answer
Slow down and give way to traffic on the major road, stopping only if you need to
The give-way sign asks you to let traffic on the major road pass first. Unlike a stop sign, you only have to stop if that traffic makes it necessary.
-

-
This sign is posted along a stretch of road. What does it mean?
Show answer
No stopping

-
What does this sign by the kerb mean?
Show answer
No waiting: you may stop only to let passengers board or alight

-

-
What does this sign mean for your speed?
Show answer

-
You are driving at 75 km/h as you pass this sign. What should you do?

What does this sign mean for the lane it marks?
Show answer
