B.On the left-hand side of the road

C.In the center of the road, moving to either side as needed

A.Overtake from the left side only

B.Overtake from either side depending on road space

C.Overtake from the right side only, except in specific situations

D.Sound your horn continuously and force the vehicle ahead to stop

Explanation: Under standard traffic rules in Sri Lanka, you should only overtake on the right side of the vehicle ahead. Overtaking on the left is permitted only in specific circumstances, such as when the driver ahead has signaled to turn right and you have enough space on the left.

B.40 km/h

C.50 km/h

B.100 km/h

C.110 km/h

D.120 km/h

Explanation: The maximum speed limit for light vehicles, such as private passenger cars, on expressways in Sri Lanka is 100 km/h. Drivers must stay within this limit and adjust their speed lower in poor weather conditions.

6What is the speed limit on the entry and exit ramps (interchanges) of Sri Lankan expressways?

A.40 km/h

B.50 km/h

C.60 km/h

D.100 km/h

Explanation: While the main carriageway of a Sri Lankan expressway allows up to 100 km/h, the entry and exit ramps at interchanges carry a reduced speed limit of 60 km/h because of their tighter curves and merging traffic.

A.Commercial dual-purpose vans

B.Three-wheelers (auto-rickshaws) and motorcycles

C.SUVs and small light utility trucks

D.Electric motor cars and hybrid vehicles

A.Traffic entering the roundabout has priority over traffic inside it

B.Traffic inside the roundabout has priority over entering traffic

C.Larger vehicles always have priority over smaller vehicles

D.Priority belongs to the vehicle traveling at the highest speed

Explanation: In Sri Lanka, vehicles already inside the roundabout (coming from your right) have priority. You must yield to traffic in the roundabout before entering it to prevent gridlock.

9What does a yellow box junction (criss-cross yellow lines) painted on the road indicate?

A.You can park your vehicle inside the yellow box for short periods

B.You must stop inside the box and wait for your traffic light to turn green

C.You must not enter the box unless your exit road or lane is clear

D.This is a special lane reserved for police and emergency vehicles

Explanation: A yellow box junction means you must not enter the box unless your exit is clear and you can cross without stopping. The only exception is when you are turning right and are prevented from doing so by oncoming traffic or other vehicles waiting to turn right.

10When two vehicles meet on a steep, narrow hill where passing is difficult, which vehicle has the right of way?

A.The vehicle traveling uphill has priority

B.The vehicle traveling downhill has priority

C.The larger vehicle always has priority

D.The vehicle moving at a faster speed has priority

Explanation: Generally, vehicles traveling uphill have priority because it is much harder for them to start moving again from a complete stop on an incline. The descending vehicle should yield and, if necessary, back up to a passing point.
