Oversize travel times, curfews and holiday restrictions

When you can legally move an oversize load — day or night, weekends, holidays — is set by each state, and the rules are surprisingly different from one to the next.

• Daylight-only — many states restrict oversize movement to a half-hour before sunrise until a half-hour after sunset, especially for wider loads.
• Continuous (24/7) — some states allow round-the-clock travel within size limits (a few, such as Tennessee, permit continuous movement by default).
• Rush-hour curfews — most metro areas bar oversize loads during weekday morning and afternoon peaks.
• Weekend and holiday bans — many states prohibit larger loads after noon Saturday, on Sundays, and around major holidays; the exact holiday list varies.
• Weather — movement stops everywhere in low visibility, high wind, or on snow and ice.
