The surveys were conducted from 10pm to 3am by the NHMRC Road Accident Research Unit in a similar manner to six previous surveys over the previous 10 years. The percentage of drivers at or above the then legal limit of 0.08 was at its lowest point in 10 years in early 1991, as was the percentage of drivers at or above 0.05. Soon after the introduction of the lower legal limit there was a 27.2% reduction in the percentage of drivers at or above 0.05. There were also reductions in the proportion of drivers at or above 0.08 (21.4%) and in those who had any level of alcohol in their blood (20.8%). However the magnitude of these early reductions in drink driving was not sustained. In the last half of the survey conducted after the introduction of the 0.05 limit the percentage reductions in both legal and illegal drink driving were between seven and eight per cent compared with the levels measured before the change in the limit. It is therefore recommended that any further change in drink driving be monitored by means of a similar roadside survey early in 1993, and that any changes in alcohol involvement in crashes also be investigated. | | Report Number | 1/92 | | Publisher | Office of Road Safety, SA Department of Transport | | Publisher City | Adelaide | | Sponsor | SA Department of Road Transport - Office of Road Safety | | ISBN | 724347305 | | Page Count | 13 | | Notes | Available from CASR library on request |
