1On which side of the road should vehicles be driven in Sri Lanka?

A.On the right-hand side of the road

B.On the left-hand side of the road

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

D.On whichever side has fewer potholes

Explanation: In Sri Lanka, traffic drives on the left-hand side of the road. This rule applies to all public roads and must be followed at all times except when overtaking or instructed otherwise by traffic signs or police officers.

2What is the standard rule for overtaking another vehicle in Sri Lanka?

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.

3What is the legal speed limit for private cars and light vehicles in urban areas in Sri Lanka?

A.30 km/h

B.40 km/h

C.50 km/h

D.60 km/h

Explanation: The maximum speed limit for motor cars and dual-purpose light vehicles within urban areas (municipal limits) is 50 km/h. Lower speed limits may be posted in specific zones such as school or hospital areas.

4What is the speed limit for private cars and light vehicles on rural and non-urban roads in Sri Lanka?

A.50 km/h

B.60 km/h

C.70 km/h

D.90 km/h

A.80 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.

7Which of the following vehicle types are prohibited from using expressways in Sri Lanka?

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

8What is the priority rule at a roundabout in Sri Lanka?

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.

LK DMT Light Vehicle Written: Suggested Study Strategy

1Learn Sri Lanka's own sign shapes: warning signs are yellow diamonds with black symbols, while prohibitory, restrictive and mandatory signs are white circles with a red border (prohibitory signs add a red bar).

2Learn the car speed limits: 50 km/h in built-up areas, 70 km/h on other roads and 100 km/h on expressways (60 km/h on ramps); three-wheelers are limited to 40 km/h.

3Know the priority rules: give way to traffic from the right at uncontrolled junctions and roundabouts, and to all traffic on a main road you are entering.

4Practise the driver arm signals: right arm straight out to turn right, moved up and down to slow down, and rotated anti-clockwise to turn left.

5Know the key numbers: 0.08 g alcohol per 100 ml of blood, parking banned 25 m (major road) or 10 m (minor road) from junctions and 30 m before bus stops and crossings, and a learner's permit valid for up to 18 months.

Frequently Asked Questions

What is the passing score for the Sri Lanka DMT written test?

The DMT does not publish an official pass mark. Driving schools and motoring guides consistently report that light-vehicle candidates answer the first 40 questions of a 45-question paper and need 30 correct; heavy-vehicle candidates also answer the final technical questions.

How is the written test conducted?

It is a multiple-choice theory test run by the Department of Motor Traffic. Since 2018 the Werahera head office has used touch-screen computers that give each candidate a randomly selected question set with a countdown timer and an immediate result. The DMT does not publish an official time limit.

What are the age requirements for a light-vehicle licence?

You may register and sit the written test after completing 17 years. To take the practical test you must have completed 18 years and held your learner's permit for at least three months.

What documents do I need to register?

Attend in person with your National Identity Card (or a valid passport carrying your NIC number), an aptitude medical certificate from the National Transport Medical Institute obtained within the previous six months, and, for a first licence, your original birth certificate. Offices using the offline system also need two black-and-white passport photographs on a white background.

How long is the learner's permit valid?

After you pass the written test, the DMT issues a learner's permit for a maximum of 18 months. You must practise for at least three months, with L plates and a supervisor aged 21 or over who holds a licence for that class, before the practical test.

What are the speed limits for cars on Sri Lankan expressways?

The Road Development Authority sets a maximum of 100 km/h on expressways and 60 km/h on entry and exit ramps. Three-wheelers, motorcycles, tractors, bicycles and pedestrians are not allowed on expressways.
