1.2 Mandatory G1 Restrictions & Accompanying Driver Rules

Mandatory G1 Restrictions & Accompanying Driver Rules

Quick Summary: Holding an Ontario Class G1 learner's permit comes with strict legal restrictions defined under Ontario Regulation 340/94. As a G1 driver, you must always drive with an eligible accompanying driver who holds a valid Class G (or higher) licence and has at least four years of driving experience. You cannot drive between midnight and 5:00 a.m., you cannot carry more passengers than there are working seatbelts, you must maintain a 0.00% blood alcohol concentration, and you are barred from 400-series highways posted over 80 km/h and certain named expressways unless your accompanying driver is a driving instructor. A conviction for violating any condition brings a 30-day licence suspension for a first offence.

Legal Framework: Ontario Regulation 340/94

When you obtain a Class G1 licence, you are granted the legal privilege of practicing on Ontario roadways, but that privilege is governed by Ontario Regulation 340/94 (Drivers' Licences) under the Highway Traffic Act (HTA).

These rules are not guidelines. They are legal conditions of your licence, and the MTO Driver's Handbook lists them as the rules you must follow at Level One. Breaking one is a novice-driver violation. On conviction it brings the escalating suspensions described below.

Restriction 1: Zero Blood Alcohol and Drug Tolerance

Ontario enforces a zero-tolerance policy for alcohol, cannabis, and illicit substances for all novice drivers:

• Blood Alcohol Concentration (BAC): Your BAC must be exactly 0.00%. Even a trace amount of alcohol detected by a roadside approved screening device (ASD) constitutes an immediate offence.
• Cannabis and Drug Tolerance: The same zero rule applies to cannabis and other drugs. Ontario's zero-tolerance law for young, novice and commercial drivers covers both alcohol and cannabis. Police can use approved roadside drug screening equipment and sobriety tests.
• Penalties (Ontario.ca impaired-driving page, updated June 30, 2026): A first occurrence for a G1, G2, M1 or M2 driver (or any driver 21 or under) brings an immediate 7-day licence suspension, a $250 penalty and an 8-hour education course. A conviction adds a $60–$1,000 fine and, for novice drivers, a further 30-day, 90-day or cancellation sanction under the escalating system. A second occurrence brings a 14-day suspension and a 16-hour treatment program. A licence reinstatement fee is charged every time your licence is suspended.
• Handbook note: The online handbook page still describes the older 24-hour roadside suspension. Study the current Ontario.ca penalties, and remember that the underlying rule has not changed: zero means zero.

Restriction 2: The Accompanying Driver Rules

A G1 driver is legally prohibited from operating a motor vehicle alone. Every trip must be supervised by an accompanying driver who satisfies four strict legal tests:

1. Licence Class and Experience Threshold

The accompanying driver must hold a valid Class G licence (or higher) and have at least four years of driving experience.

• G2 time counts: The handbook states that time spent at the Class G2 level counts toward the accompanying driver's four years, as long as the G2 licence was valid (not suspended).
• Demerit points vs. suspension: The accompanying driver's licence may have demerit points, but it cannot be suspended.
• G2 drivers cannot supervise: A Class G2 driver does not hold a Class G licence and cannot act as an accompanying driver, regardless of age or skill.

2. Physical Seating Position

The accompanying driver must occupy the front passenger seat directly beside the driver.

• They cannot supervise from the rear seat.
• The handbook is explicit: the accompanying driver is the only person who can be in the front seat with you while you drive.
• The accompanying driver must be positioned to observe the road ahead, monitor the driver's actions, and intervene in an emergency.

3. Accompanying Driver Sobriety Standards

The supervising passenger must also comply with legal sobriety thresholds:

• If the accompanying driver is age 22 or older, their BAC must remain below 0.05%. If their BAC is 0.05% or higher, they cannot legally supervise a G1 driver.
• If the accompanying driver is age 21 or younger, they are subject to Ontario's young driver zero-tolerance rule and must have a BAC of exactly 0.00%.
• If the person beside you is over the limit, they do not qualify as an accompanying driver, and you are effectively driving without one.

4. Alertness and Physical Capability

The accompanying driver must be awake, conscious, alert, and capable of taking control of the vehicle if necessary. An accompanying driver who is sleeping, intoxicated, or experiencing a medical emergency does not fulfill the statutory requirement of supervision.

Restriction 3: Nighttime Driving Curfew

Class G1 drivers are strictly banned from driving between midnight (12:00 a.m.) and 5:00 a.m.:

• This curfew applies seven days a week, regardless of weather, road conditions, or whether a parent or driving instructor is in the vehicle.
• Why this rule exists: Collision analysis by transport authorities consistently shows that fatal and severe crashes involving young and novice drivers spike dramatically between midnight and 5:00 a.m. due to reduced visibility, physiological drowsiness, and a higher prevalence of impaired drivers on the road.
• Driving at 12:01 a.m. is a direct violation of graduated licensing conditions and triggers an automatic 30-day suspension upon conviction.

Restriction 4: Expressway and High-Speed Highway Prohibitions

A Class G1 driver is strictly forbidden from driving on specific high-speed freeways and expressways across Ontario:

The Prohibited Highway Network

The handbook states the rule this way:

• 400-series highways with a posted speed limit over 80 km/h (for example Highways 400, 401, 403, 404, 407 and 427 where posted above 80 km/h).
• Named high-speed roads: the Queen Elizabeth Way (QEW), the Don Valley Parkway and the Gardiner Expressway in the Greater Toronto Area, the E.C. Row Expressway in Windsor, and the Conestoga Parkway in Kitchener-Waterloo.

The Driving Instructor Exception

The handbook gives one exception: if your accompanying driver is a driving instructor, you may drive on any road. It also says Class G1 drivers may only drive on freeways with a licensed driving instructor.

• Common Exam Trap: A parent, spouse or friend, even one with decades of experience, cannot take a G1 driver onto a 400-series highway or the named expressways. Only a driving instructor can.
• The instructor exception covers roads only. It does not lift the midnight-to-5 a.m. ban or the zero-alcohol rule.

What About High-Speed Two-Lane Highways?

Can a G1 driver operate on high-speed provincial highways that are NOT 400-series freeways?

• Yes. The restriction covers 400-series highways posted over 80 km/h and the named expressways only. With a qualified accompanying driver, a G1 driver may drive on other highways and county roads, including two-lane provincial highways posted at 80 or 90 km/h.

---

Restriction 5: Working Seatbelt Capacity

Every person traveling in a vehicle driven by a G1 licensee must have a dedicated, functioning seatbelt:

• The number of passengers is strictly capped by the number of operational seatbelts installed by the vehicle manufacturer.
• If a compact sedan has five seatbelts, the vehicle can carry a maximum of five occupants (the G1 driver, the accompanying driver, and three rear passengers).
• Sharing a seatbelt between two children or carrying an unrestrained passenger in the cargo area or truck bed is illegal and constitutes a graduated licensing violation.

Novice Driver Escalating Sanctions & Penalties

Violating any of the above mandatory conditions triggers severe statutory consequences under the Ontario Highway Traffic Act's Novice Driver Escalating Sanctions framework:

• First conviction: 30-day licence suspension, starting when you surrender your licence (you can lose your licence for up to two years if you do not hand it over), plus the fine for the offence and a reinstatement fee.
• Second conviction (within five years): 90-day licence suspension.
• Third conviction (within five years): Cancellation of your novice licence. You must reapply and start over, taking all tests and paying all fees again, and you lose any time discount, time credit and fees already paid.

The same escalating sanctions apply to a novice convicted of an offence worth four or more demerit points, or who receives a court-ordered suspension for such an offence.
