Our readings indicated an average of about one leak for every 200 miles we drove.

Readings are from June 2013 and may not reflect current leaks, due to repairs or other changes.

If you ever smell gas, or have any reason to suspect a problem, experts say to immediately exit the building or area, then call the authorities. For more see the Citizens safety page.
