Councillor Maryam Brady and Fareham Lib Dem Vice-Chair Jim Forrest are pictured at the party's conference in Brighton before joining its debate on transport policy.
The conference adopted a strategy which included a call for transport infrastructure to be incorporated with new urban and housing developments.
Maryam said: "Fareham Council has still not come up with firm and realistic plans for decent public transport to ensure its Welborne development doesn't choke our roads with thousands more cars every day.
"I'm proud to belong to a party that takes public transport seriously."
Jim Forrest added: "During the conference we were able to travel all over Brighton on frequent bus services running right through the evening. What a contrast to Fareham where huge areas have no evening or Sunday services."
