In the United States, semi-truck travel rules vary from state to state. Each state has its own regulations regarding where semi-trucks can drive, including the use of the fast lane.
In some states, such as California, semi-trucks are banned from using the fast lane on highways, except for passing. In other states like Texas, semi-trucks can use the fast lane as long as they are not carrying oversized or overweight loads.
If you're planning a road trip with a semi-truck, it's essential to check the specific rules for each state you'll be driving through.
US Regulations and Restrictions
Most states in the US do not prohibit trucks from driving in the left lane, but they do have rules to regulate its use.
Even if your state doesn't have a statewide ban, cities or local governments may impose lane restrictions on certain highways and roads. It's essential to check with a lawyer familiar with traffic laws in your area to understand the specific restrictions.
Some states, like Florida, have explicit rules against trucks using the left lane on certain highways. For example, in Florida, trucks are restricted from driving in the left lane on several stretches of six-lane interstates.
Here are some specific locations in Florida where trucks face left-lane restrictions:
- Kissimmee to Tampa International Airport: No trucks in the left lane
- Tampa International Airport to Osprey: Trucks with more than six wheels must use the two right lanes
- Florida-Georgia border to The Villages: Trucks with more than six wheels must use the two right lanes
- Fort Myers to Naples: No trucks in the left lane
- Florida-Georgia border to Jacksonville: No trucks with three or more axles in the left lane
- Jacksonville to Indian River: No trucks with three or more axles in the left lane

Tractor Trailer on Florida Highway
If you're planning to drive in Florida with a tractor trailer, it's essential to know the left lane restrictions on certain highways. Commercial trucks are prohibited from driving in the left lane on certain stretches of six-lane interstates, primarily rural sections of three interstates.
These restrictions are in place to promote motorist safety by discouraging truck drivers from weaving in and out of lanes to pass traffic. This rule specifically aims to reduce the likelihood of collisions between trucks and other traffic.
You can check the Florida Department of Transportation's interactive map to see the locations where this restriction is in place. The map will help you plan your route accordingly.

Here are the current left lane restrictions on Florida highways:
Tour buses and recreational vehicles (RVs) are not considered commercial trucks and are allowed to travel in the left or inside travel lanes of these roadways.
Services Available in California
If you're driving in California, it's essential to know the rules of the road, especially when it comes to trucks. Trucks can only use the left lane when overtaking or passing another vehicle on a freeway.
In California, there are specific restrictions for trucks on highways with multiple lanes. On highways with three or fewer lanes traveling in the same direction, trucks must use the right-hand lane. On highways with at least four lanes traveling in the same direction, truck drivers can use two right-hand lanes.
There are also designated truck-only lanes on Interstate 5 in California. If you're a truck driver, make sure to follow the road signs and use these lanes when driving on these sections of I-5.
If you're involved in a truck accident, it's crucial to know your rights and options. In California, you can consult with a knowledgeable attorney to protect your rights and pursue compensation.

If you're planning a road trip through Florida, it's essential to know about the state's truck lane restrictions. Commercial trucks are prohibited from driving in the left lane on certain stretches of six-lane interstates.
The restrictions are in place on rural sections of three interstates, primarily consisting of I-95 and I-75. Trucks are restricted from driving in the leftmost lane or the inside travel lane, leaving it specifically for automobile traffic.
Here are the current left lane restrictions in Florida: Kissimmee to Tampa International Airport, 62 miles (Mile Marker 10-72). No trucks in the left lane.Tampa International Airport to Osprey, 61 miles (MM 202-263). Trucks with more than six wheels must use the two right lanes.
Florida-Georgia border to The Villages, 139 miles (MM 467-328) is another area where trucks with more than six wheels must use the two right lanes. Fort Myers to Naples, 25 miles (MM 134-109) also has a no-trucks-in-the-left-lane restriction.

Some sections of interstates have restrictions for trucks with three or more axles. For example, Florida-Georgia border to Jacksonville, 19 miles (MM 382-363) and Jacksonville to Indian River, 173 miles (MM 333-160) both have restrictions for trucks with three or more axles in the left lane.
Tour buses and recreational vehicles (RVs) are not considered commercial trucks and are allowed to travel in the left or inside travel lanes of these roadways.
Traveling is Dangerous
Trucks traveling in the left lane can cause a number of hazards, including rear-end accidents, sideswipe and merging accidents, and devastating collisions.
A truck's blind spot to the right is much larger than the blind spot to the left, making it difficult for the driver to see vehicles traveling in the truck's right blind spot.
In Florida, commercial trucks are prohibited from using the left lane on certain parts of its highways to reduce the likelihood of collisions between trucks and other traffic.
Truck drivers who drive in the left lane expose themselves and other people sharing the road with them to a number of hazards, including traffic congestion and preventable collisions.
Here are some of the "no-zones" around a truck where the driver may be unable to see other smaller vehicles:
- Driver’s side (left of the vehicle): Under the truck cab’s side-view mirror across the width of the lane to the left
- Passenger side (right of vehicle): Under the truck cab’s side-view mirror across the width of two lanes and 10 feet beyond the length of the trailer
- Ahead of cab: At least 20 feet directly in front of the truck
- Behind the trailer: At least 30 feet directly behind the truck
Commercial trucks are equipped with multiple rear- and side-view mirrors and may have electronic blind-spot monitoring systems, which consist of multiple digital cameras mounted to the exterior of the truck to feed images to in-cab monitors.
Semi Truck Regulations
In Florida, commercial trucks are prohibited from using the left lane on certain highways for motorist safety. This rule discourages truck drivers from weaving in and out of lanes to attempt to pass traffic.
The left lane restriction helps prevent collisions between trucks and other traffic, reducing the likelihood of accidents.
Riding abreast of each other causes delays and prevents faster-moving traffic from proceeding around the trucks, making the restriction a necessary measure to maintain traffic flow.
Frequently Asked Questions
Is it illegal to ride the fast lane?
Driving in the left lane at 65 MPH or faster is only allowed for passing or when merging is not safe. Riding the fast lane without passing or safely merging can be considered illegal.
Why do semis get in the left lane?
In California, semis can use the left lane if they're traveling faster than other vehicles. However, they should only do so if they're passing slower traffic, not to maintain a steady speed.
