What sign should be used when all trucks are banned from a highway?
The R5-2 Truck Exclusion sign can be used on highways where no truck traffic is allowed. The local Town Board needs to prepare an ordinance or local law to back up the restriction.
Note that local delivery traffic can still use the highway.
The text version of the sign (R5-2a) is not allowed for use in New York State as per the NYS Supplement.
