Why is operating a non-compartmentalized tanker or single compartment with a fill level between 20% and 80% strictly restricted or discouraged unless equipped with transverse baffle plates (mure ndarëse / paravalë)?

1. Because this intermediate fill range allows maximum room for destructive liquid momentum waves to build up during braking and steering maneuvers
2. Because the tanker chassis automatically disconnects when half full
3. Because diesel engines cannot haul intermediate liquid volumes
4. Because road tolls are doubled for half-empty tankers
