Hours of Service Rules for Car Haulers: Complete Guide

Federal Hours of Service (HOS) rules for car haulers are set by the Federal Motor Carrier Safety Administration (FMCSA) and apply to any commercial motor vehicle (CMV) with a gross vehicle weight rating (GVWR) over 10,001 lbs — which covers virtually every car carrier on the road. The core limits are: 11 hours of driving time within a 14-hour on-duty window, after 10 consecutive hours off duty. Violating these limits exposes your drivers to out-of-service orders and your company to fines starting at $1,000 per violation and reaching $16,000 for the most serious infractions.

Car haulers face unique HOS challenges that standard dry-van operators do not. Loading and unloading vehicles — sometimes at multiple auction lots, dealerships, or private residences in a single day — eats into on-duty time even when the truck is parked. Understanding exactly which activities count toward which limits is the difference between a clean inspection and a violation that follows your CSA score for two years.

The Core HOS Limits Every Car Hauler Must Know

FMCSA's HOS regulations for property-carrying drivers (49 CFR Part 395) establish four distinct limits that apply simultaneously. You must comply with all four — not just the one you are closest to hitting.

The 14-hour window is the limit most car haulers run into first. Unlike the 11-hour driving limit, the 14-hour clock cannot be paused — it starts the moment you come on duty and counts every minute regardless of whether you are driving, loading, doing paperwork, or sitting in a dealer lot waiting for a signature. Plan your routes and customer appointments around this reality.

On-Duty vs. Off-Duty: What Counts for Car Haulers

Loading and unloading vehicles is on-duty, not-driving (ODND) time. Every minute you spend strapping down a vehicle, doing a pre-trip inspection, completing a bill of lading, or waiting at a pickup location counts against your 14-hour window. On a typical 7-car delivery run with stops at three dealerships, you can easily burn 2–3 hours of on-duty time that never moves the truck.

Activities and Their HOS Classification

• Driving: Counts toward the 11-hour driving limit and the 14-hour window.
• Loading/unloading vehicles: On-duty, not-driving — counts toward the 14-hour window only.
• Pre-trip and post-trip inspections: On-duty, not-driving.
• Fueling: On-duty, not-driving.
• Waiting at a shipper or consignee location: On-duty, not-driving (unless you are relieved of all responsibility and can rest freely — then it may qualify as off-duty).
• Sleeper berth rest: Off-duty (subject to split-sleeper provisions).
• Personal conveyance: Off-duty driving for personal use — not counted toward driving limits, but must be logged and is limited to moving to a safe location to rest.

The personal conveyance provision is frequently misused in auto transport. Moving an empty rig to a nearby truck stop after delivering your last car is legitimate personal conveyance. Driving 80 miles to deadhead toward your next load pickup is not — that is on-duty driving. FMCSA inspectors are trained to spot the difference.

Electronic Logging Devices (ELDs): What Car Haulers Are Required to Use

The ELD mandate (49 CFR Part 395.8) requires most CMV drivers who are required to maintain records of duty status (RODS) to use an FMCSA-registered ELD. The mandate covers any driver who operates a CMV for more than 8 days in a 30-day period. For full-time auto transport drivers, this means ELDs are mandatory — paper logs are not an option.

Who Is Exempt from the ELD Mandate

• Drivers who operate within a 100 air-mile radius of their work reporting location (short-haul exemption) and return to the same location within 12 hours — these drivers use time records instead of RODS.
• Drivers of vehicles manufactured before model year 2000.
• Driveaway-towaway operations where the vehicle being driven is part of the shipment — this is a notable exemption for some dealer-delivery operations.
• Drivers who use RODS for 8 or fewer days in any 30-day period.

ELD costs range from $25–$50 per month per device for basic units up to $80–$120 per month for platforms that integrate with dispatch, IFTA reporting, and vehicle diagnostics. When evaluating providers, verify they appear on the FMCSA ELD registry — using an unregistered device is itself a violation.

The Short-Haul Exemption: A Practical Tool for Local Car Haulers

Many car haulers operating within a metro area — moving vehicles between auction lots, between dealerships, or doing dealer trade work — qualify for the short-haul exemption and do not need to maintain ELDs or RODS at all. The exemption applies when:

• The driver reports to and returns to the same work reporting location each day.
• The driver operates within a 100 air-mile radius of that location.
• The driver does not drive more than 11 hours (or 10 hours if the vehicle requires a CDL).
• The driver is on duty no more than 14 consecutive hours.
• The driver has at least 10 consecutive hours off before the next shift.

If you qualify, your employer must maintain time records (start time, end time, total hours) for six months instead of RODS. This is a meaningful cost and compliance reduction for urban or regional auto transport operations. The moment a driver operates outside the 100-mile radius — even once that week — the exemption is lost for that day and full RODS are required.

HOS Violations, Fines, and CSA Score Impact

FMCSA enforcement uses the Compliance, Safety, Accountability (CSA) program to score carriers on seven Behavior Analysis and Safety Improvement Categories (BASICs). HOS violations fall under the Hours of Service Compliance BASIC, which is one of the most heavily weighted categories. A carrier with a percentile score above 65% in this BASIC becomes an intervention target and may face compliance reviews or operations audits.

Common Violations and Their Fine Ranges

• Form and manner violations (minor log errors): $1,000–$1,500 per violation.
• False record of duty status: $1,000–$11,000 per violation — this is the most serious HOS infraction short of a pattern finding.
• Operating beyond the 11-hour or 14-hour limit: $1,000–$16,000 depending on severity and whether it contributed to an accident.
• Pattern of HOS violations (carrier-level): Up to $16,000 per violation with potential for an unsatisfactory safety rating, which can trigger shipper contract termination and loss of operating authority.

CSA violations stay on your record for 24 months. A single serious HOS violation on a roadside inspection can push a small fleet's percentile score above the intervention threshold, triggering regulatory scrutiny that costs far more in management time than the original fine. Load boards like Central Dispatch and Super Dispatch increasingly display carrier safety ratings — a poor CSA score directly affects your ability to win loads from quality shippers.

Practical HOS Management for Auto Transport Fleets

Managing HOS compliance proactively — rather than reactively — is the difference between running a smooth operation and constantly firefighting. Here are the practices that experienced auto transport operators use:

• Build load time into route planning. If a driver is picking up four vehicles at an auction that takes 45 minutes to load, that time comes off the 14-hour clock before the truck moves. Plan driving distances accordingly.
• Set departure alerts, not just driving alerts. Your dispatcher needs to know when a driver is approaching the end of their 14-hour window — not just their 11-hour driving limit. These are two different clocks.
• Use the 34-hour restart strategically. For drivers running heavy weekly schedules, planning a full 34-hour restart (including two periods of 1 a.m.–5 a.m.) before the end of the work week resets the 70-hour clock and avoids running out of hours mid-route.
• Document waiting time correctly. When a driver is held at a dealership or auction lot, document the start and end time. If you can genuinely argue the driver was free to rest without restriction, it may qualify as off-duty — but this requires clear evidence and the driver must actually be relieved of all duties.
• Train drivers on personal conveyance limits. Misuse of personal conveyance is a red flag during DOT audits. Set a written company policy defining acceptable personal conveyance use before a compliance review asks for one.
• Audit ELD data weekly. Unresolved ELD alerts and unassigned driving segments are common findings during carrier investigations. Assign someone to review ELD data every week, not just when a violation notice arrives.

Compared to manual tracking with spreadsheets, modern fleet management software gives dispatchers real-time visibility into driver HOS status before they dispatch a load — preventing the situation where a driver accepts a run they legally cannot complete. If you are still managing HOS compliance manually, the criteria for evaluating fleet management software should include HOS visibility as a core requirement, not a nice-to-have.

Staying Compliant as Regulations Evolve

FMCSA has revised HOS rules multiple times in the past decade, most recently in 2020 when it updated the short-haul exemption radius from 100 to 150 air miles (for non-CDL vehicles) and added flexibility to the 30-minute break rule. Future changes — including potential modifications to the 34-hour restart conditions — are periodically proposed through the federal rulemaking process. Subscribing to FMCSA regulatory updates takes five minutes and ensures you are not caught off guard by a rule change that affects your drivers. If you have questions about how specific rules apply to your operation, the FMCSA provides a public FAQ and a toll-free information line at 1-800-832-5660.

HOS compliance is one of the highest-leverage areas where fleet management software pays for itself — a single avoided violation covers months of subscription cost, and the CSA score protection is worth far more over time.
