They often make frequent stops
							                                
                                        
                                    
							                        
                    
                            They usually carry fragile goods
							                                
                                        
                                    
							                        
                    
                            They are subject to lower speed limits
							                                
                                        
                                    
							                        
                    
                            They are more difficult to manoeuvre
