The Transport Committee has released a report criticising the government for not providing suitable access for disabled people on public transport.
It is calling for the Cabinet Office to organise a group to improve accessibility across government sectors.
Out of the 11.5 million people living with a disability in the country, the committee claims over a fifth - around 2.7 million - have experienced difficulties trying to use public transport.
For rail networks, it argues disabled people should not have to book their train in advance for assistance.
It is calling on the Department for Transport to deliver an accessibility action plan. Suggested changes included requiring all bus drivers to have basic training in disabilities and imposing penalties on operators advertising accessible transport but fail to do so. Incentives for fully accessible vehicles could also be introduced.
Further changes were proposed regarding EU rules, requiring airlines to offer carers free travel in cases where airlines deem a disabled person as incapable of independent travel - similar to rulings already in place in the US.
