You must signal a turn or lane change at least how far in advance?

Question: You must signal a turn or lane change at least how far in advance?

Answer options:

• 10 metres ✅ 30 metres
• 100 metres
• Only if other cars are nearby

Correct answer: 30 metres

Explanation: The ICBC Learn to Drive Smart guide states that drivers must signal their intention to turn or change lanes at least 30 metres in advance. This established safety margin provides adequate warning to other road users so they can adjust their speed appropriately. Under the British Columbia Motor Vehicle Act, signaling is legally mandatory even if no other vehicles are visible, making the "only if nearby" option incorrect. Distances like 10 metres do not offer sufficient reaction time, while 100 metres is too far and may confuse others about your intended destination. Memorizing these specific distance rules is essential for passing the ICBC knowledge test and avoiding critical errors during the Class 7 road test.
