Signs & Signals

How about an article about the detection loops in the pavement at many traffic lights? Most drivers don't know what they are for and quite often stop too far ahead or behind them.

Believe it or not, in British Columbia a yellow traffic light tells you that you must stop before you enter the intersection! Yes, I know that there is one caveat to that statement, and it is "unless the stop cannot be made in safety." The onus is on the driver that does not stop for the yellow light to show that it was unsafe if they are involved in court proceedings because of their decision.

This case decides the liability for a fatal crash at the intersection of Lougheed Highway and Nelson Street in Mission. At 5:10 am on October 10, 2016 the traffic lights at the intersection lost power and ceased to function. By 3:08 pm power had not been restored and a collision occurred that claimed the life of Barbara McNally.

I ride a motorcycle and find that some HOV lanes allow motorcycles and some do not. It is frustrating to pass the non-HOV entrance to a roadway only to find that the HOV lane entrance does not permit motorcycles. Can it be changed so that motorcycles are permitted to use all HOV lanes and entrances, in particular that one as I commute over that bridge daily?

Road Guy Rob is a civil engineer who delights in explaining traffic engineering to the public. In this episode Rob explains a bit about why these lights are placed where they are due to the horizontal and vertical angles that a driver sees.

Amid the chaos of a collision scene came a call over my police radio: "Grab that vehicle, it just drove around the cones and into oncoming traffic!" Not only did the emergency workers have to deal with a two vehicle collision in an intersection full of emergency vehicles, they also had to contend with drivers who were going through no matter what.

On a morning walk I found myself facing a young woman across a busy intersection while we waited for the traffic signal to change. She was facing me but keeping an eye on the van waiting beside her at the red light signalling a right turn. As I watched the situation unfold I was impressed with this woman's street smarts.

Here's an interesting question from the DriveSmartBC inbox: There is a mid-block pedestrian controlled traffic light in our neighborhood. Drivers frequently stop and then proceed through it if no one is in the crosswalk. Is this legal?

Question: Eastbound on Point Grey Road at Alma Street in Vancouver there are two bike lanes on the north side of the street that are allowed to cross Alma Street without stopping. On the diverter is a lane use sign for Eastbound traffic, "no straight ahead except for bicycles".
