OR
• Unit 1 = pre collision going straight and Unit 2 = pre collision turning left and any of the following
o unit 1 direction N, unit 2 direction S
o unit 1 direction S, unit 2 direction N
o unit 1 direction W, unit 2 direction E
o unit 1 direction E, unit 2 direction W
OR
• Unit 2 = pre collision going straight and Unit 1 = pre collision turning left and any of the following
o unit 1 direction N, unit 2 direction S
o unit 1 direction S, unit 2 direction N
o unit 1 direction W, unit 2 direction E
