Welcome to Fall! As the season changes, remember to slow down if you are driving on a road covered with leaves and remember that leaves make it difficult to see potholes and bumps in the road.

 Please also note that Trident Rideshare is pleased to partner with businesses to promote ridesharing.   YOU DO NOT HAVE TO CARPOOL EVERY DAY! We will happily work with companies to be give out restaurant gift certificates, water bottles and coffee cups.  

  I am here to assist if you have any questions regarding using the free Trident Rideshare registration process.  Please do not hesitate to call me at 529-0400 ext 202 or send me an email at if you need individual assistance or would like a to have a presentation/"Lunch and Learn" at your office.

 Welcome to Trident Rideshare, a free and convenient web-based service that connects commuters looking to share cars, bicycles, taxi, transit or walking trips in Berkeley, Charleston and Dorchester Counties. Sharing a ride is not only fun but it helps preserve air quality, decreases traffic congestion, conserves fuel, promotes better health and saves you money all at the same time! 

Trident Rideshare is now offering Emergency Ride Home as an additional incentive to utilize alternate transportation modes.  Emergency Ride Home offers reimbursement for rides taken by Trident Rideshare members who utilize alternate transportation modes and need an unscheduled ride home due to an emergency or unexpected event.

Trident Rideshare can help you find a compatible commuting partner by searching for others who live near you and have similar trip schedules. Contact possible commuters by email to discuss your needs and expectations. You control the personal information that is shown so you know your information is secure. You do not have to share a ride every day to participate. There is also an option for sharing a ride to community events. 

SECURITY: While you provide basic information when you register (name, address, email, and destination) this is all hidden from potential carpool matches. When notified of a possible match, all you see is a first name and last initial. You can choose to generate an email through the Trident Rideshare site suggesting you meet to decide if you want to carpool.
