Wyoming Pilot Car Requirements
When does an oversize or overweight load need a pilot car or escort in Wyoming? Here are the width, height, length and weight thresholds that trigger an escort, a height pole, or a police escort.
Escort & pilot car requirements
- Police / law-enforcement escortover 20'0" width
Wyoming Highway Patrol escort required for loads exceeding 20' wide or per permit conditions (Wyo. Stat. §31-18-301).
- Chase (rear) pilot carover 16'0" width
Second (rear) pilot car required when width exceeds 16'. Lead+chase both required on all route types (WYDOT Ch. 5 §6).
- Height-pole escortover 15'0" height
UNVERIFIED — threshold not established. Three sources give three different heights (15', 16', 17'6") and no primary WYDOT rule could be reached. Retained at the LOWEST of them so the prompt fires early rather than late; do not carry 15' to a scale as a rule. Call the WYDOT permit office or the issuing port of entry and have the pole requirement written on the permit.
- Lead (front) pilot carover 14'0" width
Front pilot car required for widths over 14' on all state highways. One escort on 2-lane (WYDOT Ch. 5 §6).
- Lead (front) pilot carover 100'0" length
Front pilot required for overall lengths over 100' on 2-lane and undivided highways (WYDOT Ch. 5 §6).
Travel restrictions
- Daylight-only travelover 14'0" width
Loads over 14' wide restricted to daylight hours (sunrise to sunset). Night travel requires special permit endorsement (WYDOT Ch. 5 §6).
- Weekend / holiday restrictionover 14'0" width
No oversize movement on New Year's, Memorial Day, Independence Day, Labor Day, Thanksgiving, Christmas. Window begins noon of preceding day for loads over 14' wide (WYDOT Ch. 5 §6).
Driver & inspection requirements
- Certified escort driver requiredover 14'0" width
UNVERIFIED — status unknown, treat as a question to ask, not a requirement. No WYDOT certification programme could be confirmed from any primary source, and the secondary sources flatly contradict each other: uspilotcars states "None noted in WY rules & regs", while the figure previously carried here cited WYDOT Ch. 5 sec. 6, which could not be read. Ask the WYDOT permit office whether a Wyoming card is needed before you hire or travel.
