This bill updates Washington’s vehicle length limits to explicitly allow longer fifth-wheel travel trailers—up to 38 feet for single-axle models and 40 feet for multi-axle models—measured from the kingpin to the rear axle. It also clarifies the definition of a fifth-wheel trailer for legal purposes.

  • Increases the maximum legal length for single-axle fifth-wheel travel trailers from no stated limit (implicitly capped by general 40-foot rule) to 38 feet, measured from the kingpin to the rearmost axle.
  • Increases the maximum legal length for multi-axle (two or more axles) fifth-wheel travel trailers to 40 feet, measured from the kingpin to the rearmost axle.
  • Clarifies that the general 40-foot vehicle length limit does not apply to fifth-wheel travel trailers, and defines them specifically as recreational units hitched inside a pickup truck bed.
  • Maintains existing length limits for other vehicle types (e.g., motor homes up to 46 feet, tractor-trailer combinations up to 75 feet).
  • Adds a new exception allowing longer fifth-wheel trailers without violating length restrictions, as long as they meet the axle-specific length measurements.

Who is affected

  • Recreational RV and travel trailer users — People who use fifth-wheel travel trailers for recreation or travel may now legally operate longer trailers on state highways, depending on axle configuration.
  • Fifth-wheel trailer owners and operators — May benefit from increased flexibility in trailer length limits, especially those using single-axle fifth-wheel trailers up to 38 feet (measured from kingpin to rear axle).
  • RV dealers and rental companies — Must ensure compliance with new length limits for fifth-wheel trailers and other combinations, and may need to verify trailer specifications when purchasing or renting.
  • Washington State Patrol and local law enforcement — Responsible for enforcing length limits on state highways and may need to update enforcement guidance or training based on the new definitions and exceptions.
  • Fifth-wheel trailer manufacturers — May need to adjust vehicle design or manufacturing standards to align with updated legal definitions and length restrictions.
Effective: March 30, 2026Fiscal impact: No significant fiscal impact identified; minor costs possible for the Department of Transportation to update rulemaking or enforcement guidance.

Pro/Con Analysis

Stronger case for benefits

Potential Benefits (4)

  • Allowing longer fifth-wheel trailers may increase housing flexibility for low- and middle-income households seeking affordable, mobile, or temporary housing options—especially in areas with high housing costs—by making longer, more livable units legally permissible on public roads.

    HousingPeopleRef: Sec. 1, subsection (1)(e)(i) and (ii)

  • RV dealers, rental companies, and small manufacturers may benefit from increased demand for longer fifth-wheel units, potentially expanding local business activity and supporting jobs—particularly in regions with strong tourism or outdoor recreation economies.

    Business & EmploymentLean peopleRef: Sec. 1, subsection (1)(e)(i) and (ii)

  • Clarifying the definition of a fifth-wheel travel trailer and exempting it from the general 40-foot limit reduces ambiguity for law enforcement and promotes consistent enforcement, decreasing the risk of arbitrary or inconsistent citations.

    Public SafetyPeopleRef: Sec. 1, subsection (1)(e)(i) and (ii)

  • The bill enables more efficient long-distance travel for recreational users by allowing longer trailers without violating length laws—reducing the need for multiple short trips or vehicle swaps, which can lower overall emissions and traffic congestion.

    TransportationPeopleRef: Sec. 1, subsection (1)(e)(i) and (ii)
Potential Concerns (3)

  • Allowing longer fifth-wheel trailers (up to 40 feet) may increase risks on narrow or winding mountain roads and in high-wind conditions, as longer trailers are more prone to sway, jackknife, and require longer stopping distances; this could endanger drivers, passengers, and other road users—especially where infrastructure (e.g., guardrails, lane width) was not designed for such lengths.

    Public SafetyRef: Sec. 1, subsection (1)(e)(i) and (ii)

  • Enforcement of the new length limits will require additional training and resources for local law enforcement and the Washington State Patrol to verify axle counts and measure from kingpin to rearmost axle—a task requiring specialized knowledge and tools—potentially diverting limited personnel from other public safety duties.

    Local GovernmentRef: Sec. 1, subsection (1)(e)(i) and (ii)

  • Longer trailers may increase wear on highways and bridges due to higher axle loads per foot of trailer length and greater turning radii, potentially accelerating infrastructure degradation and requiring earlier-than-expected maintenance or reconstruction.

    TransportationRef: Sec. 1, subsection (1)(e)(i) and (ii)

Who Is Most Affected

Low- and middle-income fifth-wheel usersMixed Impact

Low- and middle-income households using fifth-wheel trailers as affordable housing or travel options benefit from increased legal flexibility and potentially lower housing costs; however, they face higher safety risks if operating longer units on hazardous terrain.

Small-scale RV businesses (dealers, rentals, local manufacturers)Positive Impact

Small RV dealers, rental companies, and local manufacturers may see increased sales and demand for fifth-wheel units, but must invest in staff training and compliance verification—net effect likely positive for those in tourism-heavy regions.

Law enforcement agencies (WSP, local PDs)Mixed Impact

State and local law enforcement face new enforcement burdens and training needs, but benefit from clearer statutory definitions that reduce ambiguity and potential legal challenges.

Large RV manufacturers and national dealersPositive Impact

Large RV manufacturers and national dealers may benefit disproportionately if the bill spurs demand for premium, longer fifth-wheel models—though the bill’s length caps still constrain profit-maximizing designs.

Rural communities and transportation plannersMixed Impact

Rural communities and highway planners may face increased infrastructure stress from longer trailers, but also gain from increased tourism-related spending and local business activity.
