34 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Learner permit minimum age
- In Sri Lanka, a learner permit for a light vehicle (car or dual-purpose vehicle) requires the applicant to be at least 18 years old and medically fit.
- Learner permit restrictions
- A learner permit holder must display L-plates and drive only under supervision of a licensed driver for that class; solo driving is not permitted until the practical test is passed.
- Duplicate licence application
- A duplicate Sri Lankan licence is requested from the DMT with the NIC, a police report if the licence was lost, and the prescribed fee; the original licence number and classes are retained.
- Foreign licence conversion
- Converting a foreign licence requires a valid foreign licence, proof of residency status, and passing the local written and practical tests as directed; automatic exchange is not available.
- Licence class endorsement
- The classes a driver may operate are printed on the licence; driving a vehicle outside the endorsed class is an offence even if the driver holds other classes.
- Licence renewal validity
- Light-vehicle licences are renewed on a fixed cycle tied to the holder's age, requiring the existing licence, NIC, a medical certificate where age-triggered, and the renewal fee.
- Vehicle registration requirement
- Every motor vehicle used on a public road must be registered with the DMT and display compliant registration plates; registration attaches to the vehicle, not the driver.
- Ownership transfer documents
- Transfer needs the signed transfer form, Certificate of Registration, valid revenue licence, current emission certificate, and NIC copies of both buyer and seller lodged with the DMT.
- Seller liability until transfer
- The seller remains the registered owner and liable for offences and arrears until the DMT records the transfer; a private sale agreement alone does not change ownership.
- Revenue licence purpose
- The revenue licence is the annual road tax issued per vehicle class and engine capacity or weight; it must be current whenever the vehicle is used on a public road.
- Registration plate rules
- Plates must meet DMT specifications for size, font, spacing, and reflectivity; altered, decorative, or non-compliant plates are an offence and can lead to prosecution.
- Vehicle modification approval
- Engine, chassis, colour, or body-type changes require prior DMT approval and amendment of the registration record; unapproved modifications can invalidate registration and insurance.
- Left-hand traffic rule
- Sri Lanka drives on the left; overtaking is performed on the right except where lane markings permit left passing or the vehicle ahead is signalling a right turn.
- Default speed limits
- Unless signs state otherwise, the default limit is 50 km/h in built-up areas and 70 km/h outside built-up areas; expressway limits are posted and strictly enforced.
- Seat belt and helmet rules
- Seat belts are mandatory for front and rear occupants where fitted, and approved helmets are mandatory for motorcycle riders and pillion passengers.
- Legal alcohol limit
- Sri Lanka's legal blood alcohol concentration limit for drivers is 0.05%; exceeding it leads to prosecution, fines, and licence suspension or cancellation.
- Two-second following rule
- Maintain at least a two-second gap behind the vehicle ahead in dry conditions, doubling to four seconds in rain, at night, or when following heavy vehicles.
- Zebra crossing obligation
- Drivers must give way to pedestrians on or entering a marked pedestrian crossing and must not stop or park on the crossing itself.
- Mobile phone while driving
- Hand-held mobile phone use while driving is prohibited; only hands-free operation is permitted, and any hand-held use is a punishable offence.
- Uncontrolled junction rule
- At an uncontrolled junction, give way to traffic approaching from the right and to vehicles already in the junction; signal intention early and proceed only when clear.
- Sign shape meaning
- Circular signs give orders (red ring prohibits, blue mandates), triangular signs warn of hazards, and rectangular signs provide information or guidance.
- Stop sign meaning
- A red octagon requires a complete stop at the line, giving way to all traffic and pedestrians, and proceeding only when the road is clear.
- Give way sign meaning
- An inverted red-and-white triangle requires the driver to slow down, yield to traffic on the priority road, and proceed only when it is safe.
- Solid versus broken lines
- A solid white centre line prohibits crossing or overtaking; a broken white line permits overtaking when safe; double solid lines must never be crossed.
- Yellow box junction
- A yellow box junction must not be entered unless the exit is clear; stopping inside the box blocks cross traffic and is an offence.
- Traffic light sequence
- The sequence is red, red plus amber, green, amber, red; a flashing amber signal means proceed with caution and give way where required.
- Officer signals override
- Hand signals from a police officer or authorised traffic officer override traffic lights, road signs, and markings; the officer's direction must be obeyed.
- Class B licence scope
- Class B covers light motor cars and dual-purpose vehicles within prescribed weight and seating limits; it is the standard licence for private car driving.
- Class A and A1 motorcycles
- Class A1 covers motorcycles up to 100 cc; Class A covers motorcycles above 100 cc; each requires a separate practical test on a matching machine.
- Class J three-wheelers
- Class J is the specific licence category for three-wheelers (auto rickshaws); driving one without this endorsement is an offence.
- Class D passenger vehicles
- Class D covers light motor buses and passenger vehicles within prescribed limits; heavier passenger transport falls under Class DE with additional medical and training requirements.
- Class G tractors
- Class G covers light motor tractors and agricultural or construction equipment; it does not authorise driving cars, lorries, or passenger vehicles on public roads.
- Emission test validity
- Emission testing is mandatory annually for vehicles over one year old; the certificate is valid for 12 months and is required to obtain or renew the revenue licence.
- Petrol versus diesel testing
- Petrol vehicles are tested for carbon monoxide and hydrocarbons at idle and high idle; diesel vehicles are tested for smoke opacity against prescribed limits.
