Question: In British Columbia, an Approved Screening Device (ASD) measures:
Answer options:
- Speed
- Tire pressure ✅ Breath alcohol concentration
- Drug levels in urine
Correct answer: Breath alcohol concentration
Explanation: An Approved Screening Device is a roadside breathalyzer used by police officers to measure a driver's breath alcohol concentration, which helps determine if they are operating a vehicle over the legal limit. Speed is measured by radar or LIDAR systems, tire pressure requires a pressure gauge, and urine drug levels require laboratory analysis, making these options incorrect. Under the BC Motor Vehicle Act, the screening device is the official roadside tool used to enforce immediate alcohol-related prohibitions. For the ICBC knowledge test, it is highly relevant to recognize impaired driving enforcement tools and understand the consequences of failing a roadside breath test.
