Questions (5)

1. If your blood alcohol concentration is more than 80 milligrams in 100 millilitres of blood (.08)…?
  1. Your license will be suspended immediately for 30 days
  2. Your license will be suspended immediately for 10 days
  3. Your license will be suspended immediately for 90 days ✓
  4. Your license will be suspended immediately for 10 days

Answer: C. Your license will be suspended immediately for 90 days

Your licence will be suspended immediately for 90 days when your blood alcohol concentration is more than 80 milligrams in 100 millilitres of blood (.08). The handbook lists an immediate 90-day administrative licence suspension when your BAC is more than 80 milligrams in 100 millilitres of blood. It says this suspension starts at the roadside or police station and is separate from any criminal charges. That makes the 90-day immediate suspension the correct result for being over .08, while the one-year suspension described elsewhere applies after a Criminal Code conviction.

2. What should you do if you feel drowsy while driving?
  1. Open a window
  2. Stop for a short rest in a safe area ✓
  3. Turn up your radio
  4. Reduce speed

Answer: B. Stop for a short rest in a safe area

Pull off and stop for a short rest in a safe area, such as a well-lit rest stop or truck stop, and take a nap. The handbook says you cannot trick your body into staying awake when you are drowsy; you need sleep. It suggests using well-lit rest stops or truck stops, locking your doors, rolling up the windows and taking a nap. It also says caffeine, radio volume and an open window may seem to help but do not replace sleep, especially when you are sleep deprived. That is why stopping safely for rest is the reliable response rather than trying to push on.

3. Rules for both the G1 & G2 license holders include…?
  1. You can drive if your BAC (alcohol) level is below 0.05
  2. Each person in the vehicle must wear a seat belt, and you cannot drive if you have been drinking alcohol ✓
  3. You cannot drive at night
  4. You must have headlights on at all times

Answer: B. Each person in the vehicle must wear a seat belt, and you cannot drive if you have been drinking alcohol

Both G1 and G2 drivers must make sure every person in the vehicle has a working seatbelt and must not drive after drinking alcohol. The handbook's Level One and Level Two sections set the same two basic limits. A G1 driver must not drive after drinking alcohol, and the required blood-alcohol level is zero; the G2 section repeats that rule. For seatbelts, the G1 section says every person in the vehicle must have a working seatbelt, and the G2 section says the same. So the shared rules are no alcohol before driving and a seatbelt for everyone, not a small permitted alcohol level.

4. If you register a BAC from ___________ (known as the 'warn range') you will receive an immediate driver's licence suspension.
  1. .07 to .08
  2. .06 to .10
  3. .05 to .08 ✓
  4. .06 to .12

Answer: C. .05 to .08

The warn range is .05 to .08, and registering a blood-alcohol concentration in that range brings an immediate driver's licence suspension. The handbook says the warn range is a blood-alcohol concentration of .05 to .08. It also says a driver caught in that range gets an immediate roadside licence suspension. The passage gives three days for a first occurrence and seven days for a second, with a remedial alcohol-education program and increased penalties after that. So the range that triggers the immediate suspension is .05 to .08, which matches the bank answer.

5. Drivers licensed under the Graduated Driver License Program are restricted from operating a vehicle…?
  1. Without airbags
  2. During daytime
  3. With a blood alcohol concentration over .08
  4. When any amount of alcohol has been consumed ✓

Answer: D. When any amount of alcohol has been consumed

Graduated licence drivers are restricted from driving when any amount of alcohol has been consumed. The handbook passage on impaired driving states that if you have been drinking alcohol, your blood-alcohol level must be zero. That leaves no room for a small drink before driving: the restriction is tied to having consumed any alcohol at all, not to being over a particular limit. So the correct choice is the one saying any amount of alcohol has been consumed.
