No Laser, No Radar, is the Ticket Valid?

image of handheld police radarI was issued a ticket for Speed Against a Municipal Sign for driving over 30 km/h in a playground zone. The officer had no laser and no radar. She flagged me over, saying "The speed limit here is 30, you were not doing 30." I can't say whether I was doing 31 or 51. My best guess based on the location I was pulled over would be somewhere between 30 to 40 km/h.

Racing to Merge First

Q&A ImageRecently I was on Highway 97 proceeding north and about to enter Westbank when a car exiting the connector highway, 97C, came abreast of me on my right. We were in a “dead heat,” as it were, with neither vehicle as much as a car’s length ahead of the other. I felt that I had the right of way and continued at the same speed. The other car merged after me, repeatedly sounding her horn.

Q&A - Motor Assisted Cycle Ticket

Q&A ImageMy son received a traffic ticket from the police for driving without insurance and driving without a driver's licence. He was riding a bicycle that he has attached a small gas motor to and I think that this is a motor assisted cycle, not a motorcycle. If I am right, he doesn't need a licence or insurance and the police should not have issued the ticket. He has driven past police road checks with this cycle and none of them stopped him and told him that it was not legal. They should have done this first and not given him a ticket.

Determining Vehicle Speed from Yaw Marks

Yaw Striations in Tire MarkWhen a vehicle is in yaw it is rotating around a vertical axis through it's center of mass. The long, curved Y shaped marks left by the tires on the pavement were characteristic of this motion. If they were striated and of constantly diminishing radius they were of great interest for collision reconstruction because the vehicle's speed could be determined from them.
