Project: Heavy Vehicle Wheel Detachment Phase I

Reference: S0535/V6

Last update: 19/12/2008 13:36:58


The objective of phase 1 was to quantify the current frequency of wheel fixing problems and to assess the current practices within the industry in order to assess whether previous advice had a beneficial effect, and to identify new action that could be taken to reduce the scale of the problem.


The work involved:
. a survey run by VOSA and ACPO to investigate the current frequency of wheel fixing problems in the UK;

. a review of existing sources of data on wheel fixing problems;

. collection and analysis of information from other countries to assess the scale of the problem in the EU and elsewhere;

. a survey of heavy vehicle drivers, operators and manufacturers; and

. a review of current standards related to wheel fixings and procedures for wheel nut tightening.
