Question Analysis

In Alberta, the rules for using high-beam headlights are outlined in the Driver's Guide. When approaching another vehicle from the opposite direction, you must dim your high beams to low beams at least 300 metres before you meet the other vehicle. This distance ensures that the oncoming driver is not blinded by your lights, which could cause a dangerous situation. The regulation is designed to maintain safety on the road by preventing glare and allowing both drivers to see clearly.

Correct Answer Analysis

Correct Answer: 300 metres

The correct answer is 300 metres. According to the Alberta Driver's Guide, you must dim your high-beam headlights when you are within 300 metres of an oncoming vehicle. This is a specific legal requirement that helps prevent temporary blindness for the other driver, ensuring safe driving conditions.

Wrong Options Analysis

Option: 100 metres

This distance is too short. If you wait until you are only 100 metres away to dim your lights, the oncoming driver would have been exposed to your high beams for a significant portion of the approach, potentially causing glare and reducing their visibility. The legal requirement is 300 metres, so this option is incorrect.

Option: 150 metres

Similar to 100 metres, 150 metres is also less than the required 300 metres. Dimming at this distance would still leave the oncoming driver blinded for too long, increasing the risk of an accident. The correct legal distance is 300 metres, so this option is incorrect.

Option: 500 metres

While dimming your lights earlier than required is not illegal, the question asks for the specific distance at which you must dim your high beams. The legal requirement is 300 metres, not 500 metres. Choosing 500 metres would be overly cautious but not the correct answer to the question as stated.
