This study examines the nature of accidents that occurred on climbing lanes on New Brunswick's Route 2. The research was developed with a database that contained information regarding 146 accidents reported on these climbing lanes from January 1, 1987 to December 31, 1990. The characteristics of the accidents were identified along with conditions associated with each accident. Risk analysis was used to evaluate the safety associated with specific traffic manoeuvres permitted on climbing lanes. This information might be used to identify countermeasures in terms of traffic operations, and highway planning and design principles. The most significant accident risks on climbing lanes are related to overtaking when the are related to overtaking when the pavement is snow-covered or icy. Exiting from the left side of the road from the fast lane is also dangerous as is the merging in the final taper section. (A)
