Q by Macleans. What does your firm do?

A. We consult as expert witness engineers for insurance companies, plaintiffs and defendants and investigate collisions. We do the civil litigation reports.

Q by Publocc. Do you make money doing this?

A. Yes.

Q by Macleans. Do your investigations include how a highway is constructed?...Q by Publocc. How much? Tons right?

A. Absolutely. A plaintiff may try to show there is a road design defect or design issue. They must prove two things, that the road doesn’t meet standards and that the deficiency had something to do with the accident. The road authority is often brought in as a defendant and has to show there is nothing wrong with the road.

Q by Macleans. Are there any new developments making rural crossings safer?

A. Roundabouts have become popular in rural Ontario after a trial study was done at major traffic crossroads between cities. And collisions have gone down. These are not small roundabouts, they are larger than your typical intersection. Typical speeds are about 30 km per hour, but it’s better than a stop.

Q by Publocc. Roundabouts are those circle things, am I right? No "right angles," if that is the proper term? Roundabouts are "new"? Whenabouts were roundabouts invented?

C'mon man.
