What is a Traffic Control Device?

Traffic ConesAmid 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.

Lack of Driver Training

The line of cones blocking the lane might not have been seen as something the driver needed to take meaning from in this situation. I was surprised to find how little our provincial driving manuals, Learn to Drive Smart and the Tuning Up for Drivers, have to say about following the instructions of temporary traffic control devices other than to think ahead and exercise care in a construction zone.

The single mention of a traffic cone was in Tuning Up for Drivers and involved using one as a marker to practice parallel parking.

What is a Traffic Control Device?

A traffic control device can be many things including: a sign, signal, line, meter, marking, space, barrier or device. In this case, the cones would be considered a device and when placed across the lane are a traffic control device that bars traffic from proceeding.

There is a huge number of traffic control devices that we encounter when we drive every day. Signs are self evident, but it sometimes seems that the message conveyed by the type of line painted on the roadway, arrows painted on the roadway or lights, signs and barriers in a construction zone or collision scene are either confusing for some drivers or are simply seen as a guideline rather that something that must be obeyed.

Failing to Obey a Traffic Control Device

It's the driver's responsibility to know what any traffic control device they encounter while driving means and how to obey them.

Failing to obey a traffic control device may place yourself or others at risk and could result in the issue of a violation ticket. Currently that would mean a fine of $121.00 and 2 penalty points.

Sometimes it is Inconvenient

Should one drive into the oncoming lane toward a crash scene filled with emergency vehicles with flashing lights? Yes, if directed to do so by a person in authority when no other way exists to get past. Otherwise, stop and wait, or as in this case, make a left or right turn and go around the block.

Just for Fun

Here's the BC traffic sign manual from 1955.

Hi curious to know if traffic control signals are different from traffic control devices in legal terms. I would assume that traffic control signal defintion is exclusively reserved for traffic lights we normally see on intersections  (mounted on poles) that change colors at set times and alternately control traffic in different directions. Can u confirm if the Red stop sign in a regular residental street  is merely a traffic control device or also a traffic control signal. The MVA seems confusing to understand which says 

"traffic control signal" means a traffic control device, whether manually, electrically or mechanically operated, by which traffic is directed to stop and to proceed.

Thanks in advance

God bless for the great work u are doing

A traffic control signal is a traffic control device that does something, whether that action is manual, electrical or mechanical.

A metal sign on a post is a TCD but not a TCS as it is not operated in some fashion. 

Thank you for the clarification. I have also found another thread of yours where you similary mentioned that a stop sign does not qualify as a TCS when you were answering someones's Q about being ticketed for U turn on an intersection with a stop sign on cross street. 

Best regards and thanks for your this very informative portal.
