With just under a year to go until London 2012, research indicates that a third of logistics firms still have no knowledge of how the industry plans to cope with disruption during the event.
A survey conducted by the Freight Transport Association (FTA) indicates that just 5% of the sector is "totally prepared" for the problems it is likely to face in haulage and deliveries next summer.
Some 33% of respondents had no idea how the Olympic Route Network or Games Lanes will work.
As London gears up to host the world's biggest sporting event, preparations made by firms in the city should cover everything from van insurance to making sure all drivers understand the Olympic lanes system.
But the FTA warned that companies in the capital are failing to address the event's inevitable repercussions for the road transport industry.
This could cause businesses to lose revenue because of insufficient supply, which in turn could cause anger and resentment among residents and tourists alike, the group added.
Natalie Chapman, the FTA's head of policy for London, said: "How well London copes will depend largely on how well prepared the logistics sector is at managing the unique challenge it faces: making more deliveries in a much tighter time frame."
