The report discusses the records of vehicle breakdowns for the Mersey No. 1 Tunnel for the year beginning 1st April 1969. The parameters considered are breakdown frequency, cause, duration and vehicle type. The breakdown rate in this tunnel was very similar to that in other road tunnels and major surface roads in Great Britain. The overall breakdown rate found was 1 per 22,500 vehicle-km and their average duration was about 6 1/2 minutes; 1.3 per cent of broken-down vehicles remained in the tunnel for at least 30 minutes.
