So you don't breathe in the lorry's exhaust fumes
							                                
                                        
                                    
							                        
                    
                            So wind from the lorry won't slow you down
							                                
                                        
                                    
							                        
                    
                            So drivers behind can see you
							                                
                                        
                                    
							                        
                    
                            So your view ahead isn't obstructed
