Trucks turning into other lanes

[Paul]

The signs are already on the back of transport trailers. Trucks make wide turns. The hope is that while they are making that wide turn, that some impatient driver or rider doesn't try to cut inside as the truck is making its turn because that space is needed by the trailers rear wheel sweep. This turn isn't really any different. By starting from the middle lane, the truck's trailer is still going to drag across the right lane as it follows the tractor can around, but the truck driver is no longer able to keep some control over that needed sweep space. I can see people's vehicles getting crushed by the trailer's wheels as the truck tries to make the turn.

By starting from the right lane, that possibility is minimized. The truck will still have to swing wide with the cab when making the turn, but the visibility for the truck driver is a lot better and the driver has more ability to control traffic to his left when doing so. The practice of swinging wide is also specifically permitted in the HTA.

This is wrong. If there is a centre lane to turn right...the truck turning right should always use that centre lane.

As he turns right...he should direct his tractor into the far left lane on Queen....so that his trailer follows in the centre lane....

This way..there is NO traffic for him to "control" and he is no where near the right lane allowing that traffic to flow smoothly.

The issue is that the middle of the trailer will apex the curve more narrowly than the cab. If he's in the middle lane this may mean that the inside lane width gets cut in half as he hits the middle of the turn. The other effect would be for him to be forced to the far outside lane to avoid cars turning at too high a speed in the inside lane to the middle lane.

Example here of an SUV that can't turn from right lane to right lane:

Scroll the map forward and you'll see. I've almost hit dozens of oblivious people who can't make this turn.

Then why do trucks make left turns from the RH left turn lane?

There needs to be room for the tractor to square off the corner in the LH right turn lane, thus keeping the trailer tandems out of RH right turn lane. At this intersection there is plenty of room. The tractor can use part of or all of the 3rd EB lane on Queens to keep the tandems in the 2nd EB lane. If the lane is marked properly the truck would have more than enough room to make the turn properly, from the center lane into the 2nd EB lane on Queens without cutting off any traffic in the RH right turn lane. If the truck is making that right turn from the RH lane it is impossible to complete that turn without using some of the 2nd EB lane on Queens and obstructing adjascent turning traffic.

If the driver doesnt make the turn properly they may very well force car traffic up onto the curb. However thats not much different than now when trucks are apparently pushing traffic on the outside of the corner.

That dumps a slow transport truck into the middle lane of busy Queen Street, problematic in itself as far as traffic flow goes, and even more problematic when that transport now has to get back in the right lane to make the right turn onto West Drive's commercial/industrial area less than 500 meters down the street.

LOL...no..neither of those are problems. Drive one..you'll see.

IF it needs to get back into the right lane. IF it isn't making the turn on a red, which wouldn't be possible if Queen is busy anyway. Queen is a 60 Kmh limit so, if the turn is made on a green, it's of little or no consequence.

Not to mention...he's no slower than a truck going straight through the lights eastbound....

I don't think right turns should be allowed on a red from the middle lane IMO.

I agree.

I thought it was illegal for years until I actually dug into the HTA looking for it. I'll bet there have been some tickets for it too, but only after it results in a collision.

I've always wondered if it was. It's actually allowed?!

It's not DISallowed.

I tried googling who controls the signing for something like this.

I know OPP has the juriadiction on the 410 as well as the on/off ramps. I don't know if that means its a provincial thing, or regional of Peel thing.

Bingo. Nail on the head.

The signage is Provincial.

The signage is Provincial.

Thank you.
