More than two dozen drivers were charged, including three involving major non-compliance.
Other items targeted included monitoring of safety equipment such as fire extinguishers, the availability of emergency eye wash, incorrect or lack of the correct signage on the vehicle and lack of transport documents.
The roadblock also led to one driver being charged with drink driving offences.
DMP principal dangerous goods officer Peter Xanthis said it was disappointing to see drivers putting the community at risk.
He urged those who transport dangerous goods, such as chemicals, to ensure they fully complied with the law.
‘Drivers need to remember the three Ps ” placarding, |paperwork and personal protective and safety equipment,’ Mr Xanthis said.
‘There is a collaborative relationship between the DMP and Wheatbelt traffic police and this shines through in our work.’
The dangerous goods roadblocks are part of the department’s partnership with Main Roads WA to tackle unsafe transportation and improve the safety on WA’s roads.
DMP will link with other government agencies to carry out Operation AUStrans in May.
Each year, police across Australia and New Zealand work in a multi-jurisdictional enforcement operation to target road safety issues in the heavy vehicle road transport sector for such major issues as fatigue, speed and drug use. The highly successful operation has run for more than 20 years.
