Here's a simple video of an impatient driver who feels that traffic in the left lane should be moving faster.  So he proceeds to move over two lanes in a single change (he does signal though), and pass on the right.  Although I don't really agree with passing on the right, he doesn't do anything really wrong yet.  Until he moves back left, which causes the hatchback in the middle lane to tap their brakes.  The driver of the grey car then moves left another lane and puts himself between two close grouped cars in the left lane.  

I think his actions were a bit dangerous for everyone on  the road, and I don't agree with them.  But would you believe that I understand his frustration.  If we look at the road leading up to him catching up to the cars ahead of him.  We'll see that all 3 lanes are travelling at about the same speed.  This is a recipe for disaster in my personal opinion simply because people spend to much time in each other's blind spots when all lanes travel at the same speed, and North American drivers are not known for their diligent shoulder checks.  On a typical day the right lane in the express will travel at roughly 100 km/h. Traffic in the middle lane of the express will be between 105 and 110 km/h because trucks use this lane and they are speed limited in Ontario to 105 km/h approx.  Traffic in the left lane of the express will vary wildly however as sometimes it will be travelling at 130 km/h and sometimes slower than the other lanes as seen in this video.  

I'm not saying that I think the left lane of traffic should always be cruising at 130 km/h, however I do believe that 120 km/h is a reasonable speed to expect in this lane.  So in this case for the slow moving vehicles HTA 147.1 might apply.  It reads

Slow vehicles to travel on right side

147.  (1)  Any vehicle travelling upon a roadway at less than the normal speed of traffic at that time and place shall, where practicable, be driven in the right-hand lane then available for traffic or as close as practicable to the right hand curb or edge of the roadway. R.S.O. 1990, c. H.8, s. 147 (1).

 Notice how it doesn't define the legal speed limit but simply states that if you are moving slower than traffic at the time.  However I don't feel the cars travelling in the left lane should have gotten tickets for being so slow, I just think they should speed up to complete their pass and then return to the middle lane and travel at the speed they want to travel.

As for the driver of the car that passed to the right, they actually fit into HTA 172 territory.  Yes that infamous street racing law.  You might ask, "How could they fit into that, they weren't racing or doing 50 km/h over the limit!"

However if you check the definitions for street racing in the Ontario laws (Ontario Reg 455/07 Races, Contests and Stunts), you will find inside the following definition.

iii. repeatedly changing lanes in close proximity to other vehicles so as to advance through the ordinary flow of traffic while driving at a rate of speed that is a marked departure from the lawful rate of speed. O. Reg. 455/07, s. 2 (1).

Do I believe he is guilty of a street racing offence?  Not really....

But that's not up to me.

Drive Safe!
