Does the ISP provide you with the VPN traffic

I've heard rumors that some service providers can see unencrypted VPN traffic of their customers. Now I'm a bit scared on my end.  Is this true?

You can find many definitions of Virtual Private Network and not all of them are used for end-to-end encryption:
 
1. VPNs based Multi-Protocol Label Switching (MPLS) can carve virtual switched paths out of the network provider between the edge of router in order to carry the customer’s traffic. Data encryption is not provided by MPLS but it can be used as a conjunction with IPsec when encryption is required.
 
2. VPNs based on the layer Two Tunneling Protocol (L2TP) can relay dial-up sessions called PPP which is terminated by an ISP’s Network Access Server to an L2TP Gateway located in the customer’s network.
 
3. Network based IPsec VPN services usually use a carrier-class VPN switch at the provider's point of presence (POP) in order to initiate and terminate VPN tunnels across the backbone of the provider.
