Oversize Load Travel Restrictions: When Can You Move Heavy Equipment?
One of the most common surprises for first-time heavy equipment shippers is discovering that oversize loads can't travel whenever the driver wants. Every state has rules about when oversize loads can be on the road — restrictions by time of day, day of week, and holidays. These rules exist to protect the traveling public and reduce congestion, but they can add days to your shipping timeline if you don't plan for them. This guide explains the most common oversize load travel restrictions and how they affect your heavy equipment shipment.
Why Oversize Load Travel Restrictions Exist
Oversize loads — equipment exceeding 8.5 ft wide, 13.5 ft tall, or 80,000 lbs GVW — pose unique risks to other drivers and infrastructure. Wide loads reduce lane width for passing vehicles. Tall loads risk striking overhead utilities and bridges. Heavy loads stress road surfaces and bridges. States restrict when these loads can travel to minimize these risks during periods of high traffic volume.
The specific restrictions vary significantly by state, and they change frequently. What's allowed in Texas may be prohibited in California. What's allowed on a Tuesday may be prohibited on a Sunday. IronHaul's permit team tracks these restrictions for every state and builds them into route planning for every move.
The Most Common Types of Oversize Travel Restrictions
Daylight-Only Travel
Many states restrict oversize loads to daylight hours only — typically defined as 30 minutes after sunrise to 30 minutes before sunset. This is one of the most common restrictions and applies to most oversize loads in most states. Daylight-only restrictions mean that a driver who starts a move at 6 AM may need to stop at 7 PM, even if they haven't reached the destination. For long-distance moves, this can add 1–2 days to the schedule.
States with strict daylight-only restrictions include: South Carolina, Tennessee, Arkansas, Mississippi, Alabama, and most Southeastern states. Western states like California and Oregon also have daylight-only restrictions for most oversize loads.
Sunday and Holiday Travel Bans
Many states prohibit oversize loads on Sundays and/or major holidays. This is a significant planning consideration for moves that span a weekend. If your equipment needs to move from Texas to Tennessee and the route includes a Sunday, the driver may need to hold at a truck stop for 24 hours.
Common Sunday/holiday restriction states include: Tennessee, Kentucky, Virginia, North Carolina, South Carolina, Georgia, Alabama, Mississippi, Arkansas, and Louisiana. Western states including California, Oregon, and Washington also have holiday restrictions.
Major holidays that commonly trigger oversize travel bans include: New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas. Some states also restrict travel on the day before and after major holidays.
Peak Hour Restrictions in Urban Areas
Many states restrict oversize loads during peak traffic hours in urban areas, even if the load is otherwise permitted for travel. Common peak hour restrictions:
- Morning rush: 6–9 AM
- Evening rush: 3–7 PM
- Some states restrict oversize loads from entering major metro areas during both rush periods
Urban areas with strict peak hour restrictions include: Los Angeles, San Francisco, Seattle, Portland, Chicago, Atlanta, Dallas, Houston, and the DC metro area. Oversize loads in these areas often need to be timed to arrive before 6 AM or after 7 PM.
Width-Based Restrictions
Loads exceeding certain width thresholds face additional restrictions beyond standard oversize rules:
- Over 12 ft wide: Pilot car required in most states; some states restrict to daylight only regardless of standard rules
- Over 14 ft wide: Two pilot cars required in most states; route survey required; some states require law enforcement escort
- Over 16 ft wide: Superload classification in most states; extensive route survey, utility coordination, and law enforcement escort required; travel may be restricted to specific hours (often 10 PM–6 AM to minimize traffic impact)
How Travel Restrictions Affect Your Shipping Timeline
Here's a practical example of how travel restrictions can affect a move:
A 30-ton excavator needs to move from Atlanta, GA to Charlotte, NC (245 miles via I-85). The move is scheduled to start on a Friday. Here's what the driver faces:
- Friday: Departs Atlanta at 7 AM. South Carolina restricts oversize loads to daylight hours. Driver must stop by 7:30 PM — likely in Spartanburg, SC, about 180 miles in.
- Saturday: Resumes at 7 AM. Arrives Charlotte by noon. But if the delivery site is closed on Saturday, the driver holds until Monday.
- Sunday: Many Southeastern states restrict oversize travel on Sundays. Driver cannot move.
- Monday: Delivery completed.
What could have been a 1-day move becomes a 4-day move because of weekend restrictions and a closed delivery site. Planning for these restrictions in advance — and scheduling moves to start on Monday or Tuesday — can significantly reduce transit time.

Common questions
Can oversize loads travel on Sundays?
It depends on the state. Many Southeastern and some Western states prohibit oversize loads on Sundays. IronHaul checks Sunday restrictions for every state on your route and builds them into the schedule.
What is a daylight-only travel restriction?
Many states restrict oversize loads to daylight hours only — typically 30 minutes after sunrise to 30 minutes before sunset. This means drivers must stop at sunset even if they haven't reached the destination, which can add 1–2 days to long-distance moves.
Which holidays trigger oversize load travel bans?
Common holidays that trigger travel bans include New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas. Some states also restrict travel on the day before and after major holidays. IronHaul checks holiday restrictions for every move.
How do peak hour restrictions affect heavy equipment delivery in cities?
Many states restrict oversize loads during morning (6–9 AM) and evening (3–7 PM) rush hours in urban areas. Oversize loads in major cities like Los Angeles, Atlanta, and Chicago often need to be timed to arrive before 6 AM or after 7 PM.
How can I minimize delays from oversize load travel restrictions?
Schedule moves to start on Monday or Tuesday to avoid weekend restrictions. Avoid scheduling moves that span major holidays. For urban deliveries, plan arrival times outside peak hours. IronHaul builds all of these factors into every route plan.
