Fitness to qualify for a licence (official handbook)
To qualify for a driving licence to drive or ride on Singapore roads, an applicant must be at least 18 years old; must have passed the test of competence to drive; must not be suffering from mental disorder; must not be suffering from epilepsy; must not be liable to sudden attacks of disabling giddiness or fainting; must be able to read at a distance of 25 metres (with glasses if worn) a series of 6 letters and figures in white on a black background of the same size and arrangement as those prescribed for the identification mark of a motor vehicle; and must be able to distinguish the colours red, amber and green from a distance of 25 metres (SPF, Basic Theory of Driving).
The same vision and colour tests are restated as PDL application eligibility in that handbook (SPF, Basic Theory of Driving).
Licence validity
If you are a Singapore citizen or permanent resident, your driving licence will be valid for your lifetime. If you are a foreigner holding a work pass granted by MOM (examples given: Employment Pass, S-Pass, Work Permit, Dependent Pass issued with a restriction as to period of stay), your driving licence will be valid for a period up to 5 years (SPF, Basic Theory of Driving).
Foreigner photocard renewal, including rejection if the licence has been expired more than 3 years, is in application-replacement-renewal-of-driving-licence.
Drivers aged 65 and above
If you possess a valid Singapore driving licence and are 65 years old and above, you need to be certified fit to drive by a Singapore registered medical practitioner at a clinic that offers the ‘Fitness To Drive’ medical examination assessment. About 10 weeks before your 65th birthday, you should receive a letter informing you to go for a medical examination (SPF, Singapore Driving Licence).
The application/renewal page instead says that letter is sent about 8 weeks before the 65th birthday for work-pass holders (SPF, Application, Replacement, and Renewal of Singapore Driving Licence). This article records both official figures.
The examination is conducted using the Harmonised Medical Examination Report (HMER) system. Bring the notification letter to any registered clinic that offers the assessment. The examining doctor completes and submits the medical report digitally; you no longer need to upload documents yourself. You will receive an SMS acknowledgement upon submission, then outcome notifications from Traffic Police (SPF, Singapore Driving Licence).
Class 2B / 2A / 2 / 3A / 3 / 3C / 3CA: if certified fit, you are notified of validity for the next 3 years and must repeat the medical examination every 3 years. Otherwise you will be notified to surrender the licence (SPF, Singapore Driving Licence).
Class 4 / 4P / 4A / 4AP / 5 / 5P: if certified fit, you are notified of validity for the next 1 year, after passing a Proficiency Driving Test or Enhanced Proficiency Driving Test. Repeat the medical examination every year until age 74. You may book the test online on the next day via the SSDC website once the medical report has been accepted (SPF, Singapore Driving Licence).
The official handbook states the same age structure: those lighter classes cease to be valid at 65 unless the holder is certified physically and mentally fit every 3 years from 65 (65, 68, 71, 74, etc.); the heavier classes cease to be valid at 65 unless certified fit every year from 65 till 74 and the holder has passed a Proficiency Driving Test at the driving test centre (SPF, Basic Theory of Driving).
Special medical conditions or physical disabilities (all ages)
If you have an existing medical condition or physical disabilities that may affect fitness and ability to drive, SPF states that in accordance with Road Traffic Act s 37(6) or Road Traffic (Motor Vehicles, Driving Licences) Rules s 8(1)(a)–(e), you need a medical certification or memo from a Singapore-registered medical practitioner. This applies to drivers of all ages. You may also be required to undergo an additional driving assessment with an occupational therapist, accompanied by driving instructors, to verify ability to drive safely with or without vehicle modifications. Referrals for those assessments must come from a Singapore registered medical practitioner (SPF, Singapore Driving Licence).
If there are reasons to believe a motorist is suffering from a disease or physical ability that may cause him or her to be a source of danger when driving, Traffic Police will subject the driver to a medical examination at a government hospital or specialist institution; unless the motorist passes, the licence will be revoked (SPF, Application, Replacement, and Renewal of Singapore Driving Licence).
Simulator exemptions for adverse symptoms are in simulator-training-for-learner-motorists. Alcohol limits are in prescribed-alcohol-limit.
