Shadow problen in tunnel

[bigcarva]

Hello
I have a track where a tunnel goes under the road.
I'm having problems with the shadow.
I would like the shadow of the tunnel affects the car when it is inside the tunnel.
but the problem is that it does when the car rolls over
Is there a way to isolate the shadow?

Try putting an invisible wall on the roof of the tunnel and set it as a shadow caster with the shadow to fall on cars, make sure its facing up (I think its up,, if up don't work then face it down, but I'm pretty sure its up)
