South Carolina Pilot Car Requirements
When does an oversize or overweight load need a pilot car or escort in South Carolina? 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 16 ft width
Width over 16 ft: 1 front police + 1 rear police escort required, in addition to civilian front and rear escorts.
- Lead (front) pilot carover 16 ft width
Width over 16 ft: 1 front + 1 rear civilian escort required (in addition to police front and rear).
- Chase (rear) pilot carover 16 ft width
Width over 16 ft: 1 front + 1 rear civilian escort required (in addition to police front and rear).
- Lead (front) pilot carover 14 ft width
Width over 14 ft up to 16 ft: 1 front + 1 rear civilian escort required.
- Chase (rear) pilot carover 14 ft width
Width over 14 ft up to 16 ft: 1 front + 1 rear civilian escort required.
- Lead (front) pilot carover 12 ft width
Width over 12 ft up to 14 ft: 1 front escort required on 2-lane roads only.
- Height-pole escortover 16 ft height
Height ≥16 ft: 1 front escort with height measuring device (vertical height indicator) required. THRESHOLD CORRECTED 2026-09-14 from FT(16) to FT(15, 11) so the rule fires at exactly 16'0", which is what the ≥ in this detail means; it previously emitted nothing until 16'1". UNVERIFIED — the ≥ is OUR table's notation, not a quoted SCDOT sentence. SC Code of Regulations Chapter 63 (SCDOT) carries no escort provisions and the SCDOT OS/OW permit manual was not reachable for this pass. Confirm with SCDOT before relying on the 16'0" edge.
- Lead (front) pilot carover 150 ft length
Length over 150 ft: 1 front + 1 rear escort required.
- Chase (rear) pilot carover 150 ft length
Length over 150 ft: 1 front + 1 rear escort required.
- Chase (rear) pilot carover 125 ft length
Length 125–150 ft: 1 rear escort required. BAND EDGE UNVERIFIED — our table writes this band's lower bound as a round 125 ft and the rule is encoded exclusively, so it does not fire until 125'1". If the state's own text reads "125 ft or more" the trigger is one inch lower. Threshold deliberately NOT moved without primary text (reviewed 2026-09-14); confirm the band edge with the state permit office.
- Chase (rear) pilot carover 15 ft rear overhang
Rear overhang over 15 ft up to 25 ft: 1 rear escort required; red flag must be displayed.
Travel restrictions
- Daylight-only travelover 12 ft width
Over 12 ft wide: 1/2 hr after sunrise to 1/2 hr before sunset. Over 15 ft: highly restricted hours with metro-area curfews.
- Weekend / holiday restrictionover 12 ft width
Travel prohibited on New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.
