HOV / HOT (Express) Lanes Frequently Asked Questions (FAQs)


High-occupancy Vehicle (HOV) Lanes are restricted lanes reserved for vehicles with a driver and one or more passengers. Each vehicle that travels on an HOV Lane must carry at least two or, in some cases, three people. HOV Lanes allow users to travel faster and avoid congestion in regular lanes during peak periods. Motorcycles are permitted to travel on the HOV Lane at any time as per federal guidelines.

METRO converted the HOV Lane system to METRO HOT (Express) Lanes in order to make better use of an underutilized resource. During non-peak hours, single-occupant vehicles can access the HOV Lanes for a small toll.

Driving the METRO HOT (Express) Lanes FAQs

HOV / HOT traffic flow on freeway

Q: Have speeds in the HOV Lane slowed with the addition of solo drivers?
A: Daily traffic data does not suggest that speeds in the HOV Lanes have dropped due to solo drivers; however, speeds on the HOV Lanes - even corridors that have not been converted to HOT (Express) Lanes - have dropped in general. For example, the average speed on the IH-45 South HOV / HOT (Express) Lane is 59 mph from 5 - 6 a.m. and 54 mph from 6 - 6:30 a.m. Between 5 - 6 a.m. there is an average of 32 solo drivers and an average of 240 solo drivers between 6 - 6:30 a.m. Even with the significant increase in METRO HOT (Express) Lanes users during the 6 - 6:30 a.m. period, the average speed changes very little.

One of the key reasons for slower speeds on our roadways is the addition of more vehicles (both HOV and main lanes), due to a pick-up in the economy. Traffic in all corridors is currently up almost 10 percent in the lanes. With more people going to work each day, the additional cars create slower speeds across every corridor. It’s truly a double-edged sword – more people are working, but more people driving to work create more traffic.

Q: Why are the METRO HOT (Express) Lanes not open during the peak periods of traffic when solo drivers need them most?
A: First and foremost, the HOV / HOT (Express) Lane system will always give precedence to HOV users. The METRO HOT (Express) Lanes were designed to make better use of available space on the HOV Lane during periods of time when traffic is not at its peak. (How annoying is it to be stuck in a freak accident at 2 p.m. only to see an empty HOV Lane?) Unfortunately, if the METRO HOT (Express) Lanes were open during peak periods, so many people would be in the lane, it would eliminate the benefits of driving in the lane.

Q: Why are the HOV / HOT (Express) Lanes not open 24/7?
A: Good question. Because of limited freeway space, the HOV Lanes in Houston (except for the Katy Freeway) are reversible. This means they can only be opened in one direction at a time (inbound / outbound). During the week, the majority of traffic is heading into the city in the morning and out of the city in the afternoon. The HOV Lanes are operated based on that paradigm.

Thanks to automated gates and dynamic signage, the conversion of HOV Lanes to HOT (Express) Lanes offers unique opportunities for additional hours of operation.

Q: What steps is METRO taking to prohibit solo drivers from using the lanes when they are closed to METRO HOT (Express) Lanes users?
A: Enforcement the HOV / HOT (Express) Lanes system is very important to METRO. METRO Police officers are stationed throughout the HOV / HOT (Express) Lanes system to patrol for possible violators, assist with accidents in the lanes and deal with traffic flow issues. Of course, even with a high level of enforcement presence, issues can occur on the lanes that inevitably will slow down travel times.

For example:

  • An accident or vehicular problem in the lane (flat tire, animal or pedestrian in the lane, car fire, etc.)
  • A slow driver traveling between 45 - 50 mph
  • An accident in the main lanes or near the HOV / HOT (Express) Lane barrier wall, causing slowdowns in both the HOV / HOT (Express) Lanes and the main lanes

If a METRO Police officer finds a solo driver in the HOV / HOT (Express) Lane during a period when the lanes are closed to HOT (Express) Lanes users, the driver will be issued a citation.

Q: Can solo drivers using the METRO HOT (Express) Lanes also use the Diamond Lanes?
A: No. The Diamond Lanes are for HOV Lane users only. Solo drivers using the Diamond Lanes will be issued a violation.
