which lane is the passing lane in canada
Passing lane The use of passing lanes for faster traffic is sometimes acknowledged with signs using phrases such as "Slower Traffic Keep Right"[8] (in Canada, where the passing lane is to the left). In a study by the AASHTO Subcommittee on Traffic Engineering, all 24 US states involved used some form of passing lane courtesy signage, 9 of which only use those signs for steep graded roads.[9]
