Hello

I am in the process of developing a recruitment and selection process for HGV drivers.  I woud like to assess them in terms of hazad perception and highway code (theory) type questions.  I was trialling using the theory and hazard perception tests that people practice on before their test, however we did find the hazard perception part pretty difficult in order to get pass rate.  Is there anyhthing else on the market.  Can anyone guie me who to contact please.  Thanks
