Q1: When do I need a Caltrans Transportation Permit ?
for a Permit:
Permits can only be issued
for the movement of loads and/or vehicles when there exists good
cause and the loads and/or vehicles are reasonably non-divisible.
General guidelines toward divisibility are:
any load or vehicle **exceeding applicable
length, width, height, or weight
limits** which if separated into
smaller loads or vehicles would:
the intended use of the vehicle, i.e., make it unable to
perform the function for which it was intended.
the value for the load or vehicle, i.e., make it unable to
perform the function for which it was intended.
*** For a more information on legal truck size and weight limitations please click
Permits cannot be issued to circumvent the California Vehicle
Code. Permits cannot be used to allow movement of vehicles
when placed out of service for size or weight infractions.
Q2: What types of permits are available, and how much do they cost ?
Trip* ($16): 7 Consecutive
Days Duration. A single trip permit is from a single origin to a single destination
in one direction of travel.
Duration. Available for certain envelope loads or specific vehicles
on specified highways.
($90): Maximum of
90-Day Duration. Basically a single trip permit for the delivery

Q22: When do I need a direct crossing permit?
Direct Crossing Permit: Caltrans is authorized to issue a permit for a vehicle that crosses the highway from one property to another, pursuant to California law. The permit, called a Direct Crossing Permit, exempts the vehicle from registration, as long as the vehicle is only crossing the highway and not traveling on the highway. The allowable distance traveled under California law is determined on a case by case basis; there is no maximum distance in order to provide permit writers discretion in issuance of direct crossing permits. The requested route is verified by Transportation Permits Office staff.
For more information on Direct Crossing Permit please click here.
Please contact local authorities for direct crossing permits whenever there is a route which includes travel on streets, roads or highways within their respective jurisdictions.
