Concerning fifth-wheel travel trailers.
SB 5824 modifies Washington’s vehicle length laws to set specific size limits for fifth-wheel travel trailers. It allows single-axle trailers up to 38 feet long (measured from the front hitch point to the rear axle) and multi-axle trailers up to 40 feet, exempting them from the standard 40-foot overall length restriction. The bill directly affects owners of these recreational trailers, which must be hitched to pickup trucks as defined. These changes clarify permitted dimensions for safe operation on state highways without requiring additional permits.

MINOR
The bill was updated from its original introduction to a substitute version, changing the filing date and committee referral details. The most significant substantive change is the addition of a new definition for 'kingpin' to clarify how the length of a fifth-wheel travel trailer is measured, ensuring consistency with the existing length restrictions.
Scope change
The bill's scope regarding vehicle length limits remains unchanged, but the definition of how those limits are calculated for fifth-wheel trailers has been expanded to include a specific definition of 'kingpin'.
TIMELINE
The bill's reading date was updated from January 12, 2026, to February 2, 2026, and the committee referral was updated to the Senate Transportation Committee.
DEFINITION
A new definition for 'kingpin' was added to clarify that it is the metal pin at the front of the trailer used for steering and connection, which is essential for calculating the trailer's overall length.
A new subsection (4)(c) was added to specify that the length of a fifth-wheel travel trailer is measured from the center of the kingpin to the rear of the vehicle.
