THE QUEBEC GRADUATED LICENSING SYSTEM FOR NOVICE DRIVERS: A TWO-YEAR EVALUATION OF THE 1997 REFORM
Bibliographic record
Abstract
Since July 1997, the revised Quebec graduated licensing system (GLS) encompasses a learning period (accompanying rider, zero BAC and ceiling of 4 demerit points) of 12 months for all new drivers, with the possibility of reducing it to 8 months by taking a driving course, and a probationary period (zero BAC and ceiling of 4 demerit points) of two years applying only to drivers under 25 years of age. Prior to the 1997 reform, the Quebec GLS had only minor restrictions (ceiling of 10 demerit points instead of 15 for a regular licence). This paper presents an evaluation of the 1997 reform using a before/after design (2 years/2 years) with a comparison group. The record of the GLS group (learner and probationary) is compared to a non-GLS group composed of all young drivers (18-24 year-olds) holding a regular licence. Using the same design, preliminary results have shown that the net one-year effect of the revised GLS was to reduce fatalities by 32.8% and injuries by 15.1%. The two-year evaluation found a 4.9% reduction in fatalities and a 14.4% reduction in injuries. Possible reasons for this disparity between results are discussed and for the first time, the study evaluated the impact of Zero Alcohol on collision involvement.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
