Vehicle restriction signs

[ACtrafficengr]

We have an intersection where large vehicles are off-tracking into a dry-laid stone wall on one corner. I'm getting pressure to come up with a restriction to prevent it. The MUTCD mostly has truck weight restriction signs, and I need something to prohibit longer vehicles that can't make the turn.

Any ideas for a workable sign?

Most of the culprits have apparently been driving tractor trailers and school buses. I'd really rather not prohibit the latter. I think an engineering solution may work better than a regulatory one. I'm going to push some minor widening instead, but we don't have a lot of ROW.

Is there an alternate route trucks can use to access the area? If so, I would start with a No Trucks Allowed sign (R5-2 and maybe R5-2a) , combined with the intersection ahead sign (W2-1/W2-2).

You may need to visit bus dispatch offices and explain to them and their drivers to not turn here.

If this is the only access point, and the stone wall and building are to be protected, both roads will likely require widening to accommodate the larger vehicles.

Good luck on this one.

Are there legitimate reasons for those trucks going that way? Do they have an alternative?

Seems to me that you could just crop a k-rail on the lane divider and that would do more to stop anyone than any signage might.
