references and resources Vision and medical screening  Learner stage driving restrictions  driving tip 138 •  Restricted driving hours  — you may drive only between 5 a.m. and midnight. •  Passenger limit  — only two passengers may be in the vehicle  with you: your supervisor and one additional passenger.  •  L sign  — you must display the official L (Learner) sign in your  back windshield or on the rear of your vehicle when you are  driving. It must be visible to drivers behind you. We’ll give  you this sign when you get your learner’s licence.  •  No hand-held or hands-free electronic devices  — you must  not use hand-held or hands-free communication devices  (for example, cellphones, music or portable gaming devices,  GPS systems) while driving. •  Zero blood drug concentration  — you must not operate  a motor vehicle while having the presence of certain drugs,  including cannabis (THC), in your body.  •  Zero blood alcohol content  — you must not drive after  consuming any amount of alcohol.  •  Qualified supervisor  — a qualified supervisor must sit beside  you when you are driving. Your supervisor must be 25 or  older and hold a valid Class 1, 2, 3, 4 or 5 licence.  Your vision will be checked to make sure you can see enough to  drive safely. You’ll be tested for colour vision, depth perception,  field of vision, diplopia (double vision) and sharpness of vision.  You may need to have further vision testing by an optometrist  or ophthalmologist if you don’t pass the vision screening. If you  need to wear glasses or contact lenses when you drive, this  restriction will be shown on your licence. You will also be asked about your medical condition. If there is  any question about your physical ability to drive, or if you have a  progressive medical condition, you may need to go to a doctor  for a medical examination. Your doctor’s report will be sent to  RoadSafetyBC. The final decision whether to issue you a driver’s  licence will be made there. While you are driving with a learner’s licence, you must follow  these restrictions:  Free replacement L signs  are available at any  driver licensing office.  You can also download  a temporary L sign from  icbc.com.
