4. _Lighting Regulations._--Three lamps must be carried. The front one, on left (off) side, to show a green light; the tail-light to be on left side, and to efficiently illuminate the number-plate. These lamps must be lit not later than fifteen minutes after sunset. 5. _Rule of Road._--Keep to right, overtake on left. 6. A bell or horn must be used, but the use of sirens is forbidden. 7. There is a uniform speed-limit of 30 kilometres (about 18 miles) per hour, but this is rarely, if ever, enforced, except in and about the towns. Special speed-limits are often in force in towns and villages, notices to this effect being displayed. 8. Octroi duties for petrol have to be paid on entering Paris and some of the larger towns. The officials, except in the case of Paris, require you to pay only on the spare petrol--_i.e._, that not in the petrol-tank proper. * * * * * With regard to the daily mileage covered, as shown in the log, the writer thinks that to properly enjoy the tour, and to do justice to what there is to see _en route_, one should take at least twice the twenty-eight days, especially if the party consists of more than two or three. Otherwise, for a man driving and looking after his own car, no matter how reliable, the trip might become too arduous for enjoyment, the opportunities for sight-seeing, as this book demonstrates, being enormous. If possible, all night-driving should be avoided. In the dark one cannot see the broken glass and rubbish in the villages, nor is it easy to find the right road. Even with a certain amount of night-driving the tour described in this book was accomplished with a very small outlay in tyres, which were Dunlops. Five new covers and an old one on the Stepney wheel and eight air-tubes were found to be ample, owing to the excellent manner in which they stood the strain of rough surfaces and sometimes fast driving.
