On behalf of 480 members in the safety agency, Prospect negotiator Helen Stevens said: "The union remains as ever, ready, willing and able to engage in constructive negotiations around enabling new working practices and rewarding staff appropriately.
"We welcome the recognition that the pace of change should be slowed to allow that to happen, properly informed by evidence on customer needs.
"Our members have already contributed to the transport policy work. The select committee said the UK's HGVs and PSV road safety record is testament to the high standards of VOSA's testing staff.
"We hope that the department will respond positively to the report's recommendations, in particular the call for market research into whether operators are experiencing delays when booking tests and work to explore whether there is a demand for more night-time and weekend working."
