Alcohol drugs
1. As a G1 driver, your permitted blood alcohol concentration is:
Answer: D. G1 and G2 drivers must have zero blood alcohol — none at all — whenever they drive. The fully licensed adult limit does not apply to learner or novice drivers. Prescription or illegal drugs that impair ability are also prohibited. One drink can be enough to breach zero tolerance rules and trigger immediate roadside consequences.

Demerit points
2. Accumulating too many demerit points can result in:
Answer: A. Demerit points record convictions for certain offences. Exceeding the provincial threshold can lead to suspension of your driver's licence, with longer suspensions for repeat or novice drivers. Points also affect insurance costs. New drivers face stricter thresholds, so a single careless-driving conviction can already threaten a G1 or G2 privilege.

Emergencies
3. You see a fire truck or ambulance approaching from behind with lights and sirens. You should:
Answer: B. When an emergency vehicle approaches with flashing lights and siren, keep a safe distance (at least 15 m when it is stopped, and avoid tailgating when following), then pull over to the right edge of the roadway and come to a clear stop when safe. Do not block an intersection. Only move again when the vehicle has passed and the way is clear.

Intersections turns
4. Before turning left at a green light, you should:
Answer: C. A left turn is only allowed when you can complete it without conflicting with oncoming vehicles, transit, cyclists, or pedestrians. Signal early, position safely, wait for a clear gap, and never assume oncoming traffic will slow. A green light permits the turn but does not give you right-of-way over those already lawfully in or crossing the intersection.

Licensing g1
5. To apply for a G1 licence you must be at least:
Answer: A. Applicants must be at least 16 years old, be an Ontario resident (not merely a visitor), pass a vision test, and pass a knowledge test on the rules of the road and traffic signs. After passing you enter Level One with a Class G1 licence. Age alone is not enough — residency and the two tests are equally required.

Parking
6. When parking downhill next to a curb, you should turn your front wheels:
Answer: A. Park downhill with the front wheels turned toward the curb so a rolling vehicle is caught by the curb rather than rolling into traffic. Uphill (without a curb) the usual advice is wheels turned away from the curb or toward the shoulder, depending on configuration. Always set the parking brake. The curb is your backup if the transmission fails.

Right of way
7. You are approaching an all-way stop. Two other vehicles arrived at the same time as you. Who goes first?
Answer: C. At an all-way stop, if two or more vehicles arrive together, the driver on the right has the right-of-way. Size, impatience, or signalling does not change that rule. If you arrived clearly first, you proceed first; if arrival is simultaneous, yield to the right, then continue in a courteous, predictable order so nobody assumes a different turn sequence.

Road signs
8. An octagonal red sign always means what?
Answer: C. An octagon is reserved for one meaning: stop. Drivers must bring the vehicle to a complete halt at the limit line or before entering the intersection, then proceed only when safe. Other shapes carry different jobs — a triangle warns or yields, and a rectangle usually regulates — so shape alone is a reliable clue when visibility is poor.

Sharing road
9. When a school bus with flashing red lights is stopped on your side of a divided road, you must:
Answer: D. A school bus stopped with alternating red flashing lights requires traffic to stop until the lights cease flashing, regardless of whether you can see children. On a physically divided highway, rules can differ by configuration, but the safe and legal habit is to stop when the bus signals loading or unloading. Failing to stop endangers students and carries heavy fines and demerit points.

Speed limits
10. Unless otherwise posted, the maximum speed limit in most built-up (urban) areas in Ontario is:
Answer: A. The default urban maximum is 50 km/h when no sign states another limit. School, construction, or posted residential zones may be lower (for example 30 or 40 km/h). Always obey a posted sign over the default. Speed must also be reasonable for traffic, weather, and road conditions even when you are at or below the limit.

Alcohol drugs
11. The general adult impaired-driving limit in Ontario for fully licensed drivers is a BAC of:
Answer: C. Fully licensed drivers face impaired-driving charges at 0.08% BAC or higher for the criminal offence threshold commonly referenced in study materials, while warning and roadside administrative thresholds can apply at lower levels. Learner and novice drivers remain at zero tolerance. Because impairment begins before 0.08%, the only safe choice is to plan a sober ride before you drink.

Demerit points
12. Careless driving is a serious offence because it:
Answer: C. Careless driving means operating a vehicle without due care and attention or without reasonable consideration for other road users. Courts treat it seriously: substantial fines, demerit points, and possible suspension follow convictions. Distracted behaviours — phone use, eating, adjusting controls blindly — often escalate into this charge when a collision or near-miss occurs.

Emergencies
13. When following an emergency vehicle responding to a call, the recommended minimum following distance is about:
Answer: A. Guidance is to keep roughly 15 metres (about 5 car lengths) behind an emergency vehicle using lights and siren when you cannot yet pull over, and never follow closely as if drafting. This buffer gives you reaction space if the unit stops short or manoeuvres. Once you can safely move right and stop, do so until it passes.

Intersections turns
14. When making a right turn on red, you must first:
Answer: A. A right turn on red is not a rolling yield. You must stop fully behind the stop line or crosswalk, then turn only when the way is clear and no sign prohibits the turn. Yield to pedestrians in the crosswalk and to traffic with the green. If visibility is blocked, inch forward only when safe, then complete the turn.

Licensing g1
15. A Class G1 driver may drive only when:
Answer: B. G1 drivers must never drive alone. The front-seat passenger must be a fully licensed driver with at least four years of driving experience and a blood alcohol level under 0.05 (zero if that driver is 21 or under). That person must be the only other occupant of the front seat. Violating these conditions risks roadside charges and licence consequences.

Parking
16. You must not park within how far of a crosswalk at an intersection?
Answer: C. Parking that blocks a crosswalk, stop sign sightline, fire hydrant access, or sidewalk is prohibited. Exact metric setbacks vary by provision and municipality, but the principle is fixed: never park where you hide pedestrians from drivers or force them into traffic. When in doubt, choose a legal marked stall — convenience is not a defence.

Right of way
17. When entering a roundabout, you must yield to:
Answer: C. Traffic already in the roundabout has priority. Approach in the correct lane, slow, and enter only when there is a safe gap. Do not stop inside the circle unless traffic conditions require it, and do not change lanes within the roundabout. Signalling your exit helps other drivers, but yielding to circulating traffic is the non-negotiable rule.

Road signs
18. A sign shaped like an inverted triangle (point down) tells you to:
Answer: A. The upside-down triangle is the yield sign. You slow down, give the right-of-way to vehicles and pedestrians in or approaching the intersection, and stop only if needed. It is the only sign with this shape, so even when paint is faded the outline still communicates yield rather than stop or warning.

Sharing road
19. A cyclist is riding near the right edge of the lane ahead of you. You should:
Answer: B. Cyclists are vehicles with the same right to use the road. Pass only when it is safe to give roughly a metre of clearance (more at higher speeds), signal, and return to your lane without cutting them off. Do not require them to use a sidewalk. Patience and space prevent dooring and right-hook crashes at intersections.

Speed limits
20. Outside cities and towns, the default maximum speed on many open roads is:
Answer: D. Rural or unincorporated stretches often default to 80 km/h unless signed otherwise; urban default remains 50 km/h. Freeways and 400-series roads usually post 100 or higher where allowed. Never treat the default as a target in bad weather — you must still reduce speed so you can stop within the distance you can see to be clear.
